First step of the simplification review. No behaviour change. - Unreachable paged-month path (`MonthContent` / `MonthPager` / `MonthPage`); the month branch is now scrolling vs split - `ui/day/` and its test, `MonthViewModel.anchorPage`, `PagedTimelineViewModel.goToDate`, `SettingsPrefs.setQuickSwitchConfig`, `TimelineHours.span` - `PermissionViewModel` / `PermissionUiState`, replaced by a saveable `denied` flag in `PermissionScreen` - `ReminderNotifier.post` no longer returns a value nobody read - 38 unused imports outside the widget code Co-authored-by: Jean-Luc Makiola <business@jeanlucmakiola.de> Reviewed-on: https://codeberg.org/jlmakiola/calendula/pulls/407
