Tighten report widget selection and dashboard layout rendering - #1556

Report widgets may declare a `permissions` key. `WidgetManager::listReportWidgets()` applies it, the add-widget popup offers only what it returns, and `makeReportWidget()` builds only what it contains -- but `ReportContainer::onAddWidget()` took the class name from the request and constructed it regardless. It now works from that same list, and consults it before the class name is used for anything else, so every name that is not on it gets the same answer. `listReportWidgets()` now applies the permission filter to a copy rather than to its own memo: the widget manager is a singleton for the life of the process, so filtering the memo hid a widget from every later caller in that process, including one acting as a user who does hold the permission. The container renders two of a layout's stored values into attributes of its own, the column count and the sort order, and a layout can be published to every other backend user by a holder of `backend.manage_default_dashboard`. Every sort order the container derives or stores is now an integer, both values are compared and rendered as integers, the remaining values in both container partials and in the toolbar partial they include are escaped, and `onUpdateWidget()` keeps only the properties the container publishes for the widget -- the same set it offers the inspector -- refusing a payload it can make none of those values out of rather than applying it as an empty set, which would replace the widget's configuration with its declared defaults. Typing the container's own two values also keeps a dashboard renderable when a layout stored earlier holds something other than a number in either of them. A report widget's title gets the same treatment, through a new `ReportWidgetBase::getTitle()` that the three core report widget partials use. `trans()` resolves a key naming a translation group to an array rather than a string, which cannot be rendered, so a title of that shape stored in a published layout made every dashboard serving that layout unrenderable -- including the toolbar that would have let it be reset. The configured value is now rendered as written whenever translating it does not produce a string. Behaviour changes: - A report widget class that is not on the list the current user may add is refused by `onAddWidget()`, with the same answer whether it is unregistered, misspelled or permission-restricted. - `onUpdateWidget()` stores only the properties the container publishes for that widget at the time of the request. A widget whose declared property set depends on one of its own values will not have a property stored in the same request that first publishes it; posting the two changes in sequence stores both. - A stored column count or sort order that is not a number is rendered and compared as an integer rather than as written. - A title whose translation key names a group renders as the configured text instead of failing the dashboard. - `onRemoveWidget()` and `onSetWidgetOrders()` are unchanged: both act only on keys already present in the acting user's own stored layout and construct no widget, so neither reaches the permission filter. (The internal note that said all four handlers resolve through `makeReportWidget()` was wrong about these two.) Covered by `Backend\Tests\Widgets\ReportContainerSecurityTest` (38 tests) and two cases added to `Backend\Tests\Controllers\IndexSecurityTest`, including `testTheContainerAndItsToolbarEscapeTheContainerAlias`, `testATitleNamingATranslationGroupStillRendersTheDashboard`, `testTheWidgetListIsNotHiddenFromALaterUserInTheSameProcess` and `testTheStoredWidgetWidthIsAnInteger`. 30 of the 38 fail without the production changes.

WalkthroughReport-widget operations now validate widget classes and submitted properties, and normalize layout widths and sort orders. Dashboard templates escape rendered attribute values. Widget headings use a shared title method, and permission-filtered widget listings no longer alter the manager’s stored list. Inspector class requests are checked against offered classes. Tests cover these changes and Inspector handler access responses. Priority: ➖ Normal Estimated code review effort: 4 (Complex) | ~40 minutes Possibly related PRs

`InspectableContainer::onInspectableGetOptions()` took `inspectorClassName` from the request and used it twice before deciding whether it was a name the controller had any business with: `class_uses_recursive()` autoloads whatever it is handed, and the reflection below it constructed the class -- with the declared default for every optional constructor argument and `null` for every required one -- for anything using `System\Traits\PropertyContainer`. The name is now resolved first against a new `listInspectableClasses()`, which returns the registered report widgets and the registered components. Those two registries are what decide whether a `data-inspector-class` is rendered at all: the report container partial, the CMS component form widget partial and the CMS component list each take their value from one of them, and `ReportWidgetBase` and `ComponentBase` are the only two classes in core using the trait the handler requires. The method is `protected`, so a controller that publishes an inspectable class of its own adds it. The CMS half is behind `class_exists()` because `winter/wn-backend-module` does not require the CMS module, the same guard `BackendController` already uses. Matching is on the normalised, lower-cased class name: `class_uses_recursive()` and `new` both accept a leading separator and any casing, so comparing case-insensitively admits exactly the same set of classes while closing the spelling gap. Resolving before the name is used also means a name that does not resolve no longer reaches `class_parents()`, which returns `false` and leaves `array_reverse()` to raise a `TypeError` -- a response that differed from the handler's own refusal even with `APP_DEBUG=false`, and so reported whether a class existed. `ReportContainerSecurityTest`'s unregistered report widget now records its own construction. The tests around `onAddWidget()` asserted on persistence and on the refusal text, both of which stay green if the registry check moves back below `new $className($this->controller)`. Behaviour changes: - `onInspectableGetOptions()` answers only for a registered component or a registered report widget. Every other name gets the same refusal, whether it exists, exists and is not inspectable, or does not exist. - A controller mounting the trait that inspects a class in neither registry overrides `listInspectableClasses()` to add it. Covered by `Backend\Tests\Traits\InspectableContainerSecurityTest` (9 tests, 5 of them failing without the production change) and by the construction assertion added to `ReportContainerSecurityTest::testUnregisteredClassCannotBeAdded`.

`onUpdateWidget()` passed `Request::input('fields')` straight to `json_decode()`, so `fields[]=x` raised a TypeError rather than being refused. Guard on `is_string()` and let the existing refusal handle it.
Also tightens the comments across this branch, and pins `app.debug` in the two tests whose assertions read the refusal reason off the error page — the reason is only rendered in debug, so they failed against a local `.env` that turns it off.

ReportContainer::onAddWidget()took a class name from the request and constructed it, rather than working fromWidgetManager::listReportWidgets()— the permission-filtered list thatonLoadAddPopup()offers andmakeReportWidget()builds from on every other path to the same widgets. It now consults that list before the name is used for anything else, so a name that is not on it gets one answer whether it is unregistered, misspelled or filtered out.listReportWidgets()filters into a copy rather than into its own memo. The manager is a singleton for the life of the process, so filtering the memo hid a widget from every later caller, including one who does hold the permission.Backend\Traits\InspectableContainer::onInspectableGetOptions()had no equivalent list, and bothclass_uses_recursive()and the reflection below it reach the class — the first autoloads it, the second constructs it. The name now resolves first against a newlistInspectableClasses(), which answers from the registered components and the registered report widgets: the two base classes those registries hold are the only ones in core using the trait the handler requires, and they are also what decides whether adata-inspector-classis rendered in the first place. It isprotected, so a controller publishing an inspectable class of its own adds it — the one upgrade step this imposes on plugin authors. Across 786 marketplace plugin builds, no plugin defines a class usingSystem\Traits\PropertyContaineroutsideComponentBaseandReportWidgetBase, and every third-party supplier of an inspector class — the Pages snippet editor in both of its forks, Indikator.DevTools, Inetis.RicheditorSnippets — supplies a registered component, so the list admits all of them.The container renders stored layout values into attributes of its own. Sort orders and column counts are now integers wherever they are derived, stored, compared and rendered, and the remaining values in the container and toolbar partials are encoded. The encoding is applied on output as well as constrained on input, because an existing installation may already hold a stored value.
onUpdateWidget()keeps only the properties the container publishes for that widget.ReportWidgetBase::getTitle()falls back to the configured value whentrans()resolves the key to an array. A title naming a translation group otherwise made every dashboard carrying it unrenderable — including the toolbar that would have let it be reset.Neither handler is a regression; both date from the initial import.
