Add app info button

[RKBoss6]

This PR adds:

• a button in each app tile for app information
• The modal showing:
  • Installs
  • Favorites
  • Device Compaibility
  • (if available) Author
    The reason behind this PR is to add a dedicated menu for each app's information, rather than showing it through a tooltip that won't support mobile users.

I've kept the tooltip intact for now so as to not change too much for users who are still used to the tooltip hover.

It's up on my app loader

Changes:

• Introduces showAppInfo(...) to display an “App Information” modal per app.
• Refactors tooltip/app metadata construction into a shared getAppInfo(app, expanded) helper.

I'm not sure if they see this, so @bobrippling and @thyttan - any thoughts?

Personally I'm not super convinced by this - another button makes the app screen look very crowded - and I'm not sure this really solves a problem anyone was complaining about (although can see you can't get the tooltip when on mobile?)

What about keeping the tooltip (it might have to be moved to an actual HTML element as you've done here), but allowing tapping on the app's icon/title to bring it up rather than having a new icon? That way it's not really breaking/changing anything for existing users, but is allowing access on mobile devices.

[RKBoss6]

Yes, that sounds good, and was actually what I was thinking of doing originally. At least for iOS (not sure about android) there's no way to display tooltips on mobile without custom css tweaks, so I'm thinking we keep the modal and show it when the title/icon is clicked.

Or... we just slap it all into the top of the 'ChangeLog' popup menu? And maybe a 'report issue' button that uses the GitHub file issue link (https://github.com/espruino/BangleApps/issues/new?template=bangle-bug-report-custom-form.yaml&fwversion=...&apps=...) with the author info we now have

Maybe it's overkill having two separate menus for what's effectively just 'app info'

[RKBoss6]

Yeah, I actually like that idea a lot - so instead of showing the changelog history, we show an "app info" modal that has all the information and the changelog. If we want to clean things up even more, we could put the github link in the modal as well instead of in the app tiles, but I'll work on these changes now!
