1) Burger menu (and other bottom sheets) had rows hidden behind the system navigation bar: MainActivity never called enableEdgeToEdge(), so the sheets' navigationBarsPadding resolved to 0. Enable edge-to-edge and place the insets ourselves — top bar statusBarsPadding, content/FAB navigationBarsPadding, auth screens systemBarsPadding — and add navigationBarsPadding (+ imePadding for the editor) to the Filter/Groups/Accounts/Editor sheets. 2) The calendar filter only listed calendars that had events in the loaded range, so empty calendars couldn't be toggled. Load the full calendar list from all sources (loadAllCalendars) and merge it with the event-derived entries — matching iOS, which already shows the complete list.
