Blazor Hybrid follow-up PR

To aid in getting #1320 merged sooner rather than later, this issue tracks non-crucial planned changes that can be done after it's been merged.

• Rename FwLiteDesktop to something like FwLiteMaui (4dceaf47327a3163cd5e243bc51308143ed40167)
• Rename LocalWebApp to FwLiteWeb (70506656f2698053be437a21d159c2716b188f8e)
• Explicitly save fwdata after each change fixed by #1358
• Pull out svelte routing library? Or just figure out the best way to navigate to a sub-route e.g. view config and permission pages maybe a sync status page (or should that be a modal? Either way it'll probabably be full-screen on mobile, so should work with the back button).
• Rework invokeOnWindow: queue invocations for handlers that don't exist yet and probably use events to know when they're ready
  • Should fix: F5 not working on some projects
• Rework JS/.NET EventBus bridge
• Once invokeOnWindow is refactored, is there any more messy JS we can turn into TS or otherwise cleanup? e.g. in SvelteLayout.razor
• Fix LocalWebApp
• Fix supported-feature handling see: https://github.com/sillsdev/languageforge-lexbox/pull/1320#discussion_r1893598266
• Fix Android app icon and splash screen
• Fix disposing MauiApp service provider (e.g. fwdata lock file currently remains in place), fixed by #1358
