fix: Tags column can't be shown/hidden (#281)

The Show/Hide Columns menu had no Tags checkbox, and 'tags' was absent
from the column-visibility listener list, defaults map, and class map —
so the column couldn't be toggled at all. Added the checkbox (in column
order) and wired tags through parseColumnVisibility/applyColumnVisibility/
the change-listener list. Existing users default to tags visible.

 ### Fixed
 - Dropdowns in the transaction list (the column-configuration gear menu and the in-cell category/tag/account editors) were cut off when the table had only a few rows, because the table area was shorter than the dropdowns. The transaction table now fills the available height, so every dropdown has room to open in full ([#280](https://github.com/otherworld-dev/Budget/issues/280))
+- The Tags column couldn't be shown/hidden — the Show/Hide Columns menu was missing a Tags entry, and the column wasn't wired into the visibility logic. Tags can now be toggled like the other columns ([#281](https://github.com/otherworld-dev/Budget/issues/281))
