Subject: feat: refactor UI to BottomNavigationView with Safety and Doc
 fragments

Replace FAB-based navigation with a 4-tab BottomNavigationView (Map,
Instruments, Log, Safety). Instruments use a collapsible bottom sheet;
Log and Safety display as full-screen overlay fragments.

- Add SafetyFragment with MOB and Anchor Watch controls
- Add DocFragment for in-app markdown help (Markwon: core, tables, images)
- Add layout_instruments_sheet with 3x3 instrument grid and PolarDiagramView
- Add fragment_safety and fragment_doc layouts
- Add vector drawables: ic_map, ic_instruments, ic_log, ic_safety, ic_close
- Update activity_main.xml to CoordinatorLayout with bottom sheet + overlay
- Fix: set isHideable=true before STATE_HIDDEN to avoid silent no-op from
  behavior_hideable=false default; restore false on Map/Instruments tabs
