Subject: feat: add AnchorWatchHandler UI with Depth/Rode Out inputs and
 suggested radius

- Add AnchorWatchState with calculateRecommendedWatchCircleRadius, which
  uses ScopeCalculator.watchCircleRadius (Pythagorean scope formula) and
  falls back to rode length when geometry is invalid
- Add AnchorWatchHandler Fragment with EditText inputs for Depth (m) and
  Rode Out (m); updates suggested watch circle radius live via TextWatcher
- Add fragment_anchor_watch.xml layout
- Wire AnchorWatchHandler into bottom navigation (MainActivity + menu)
- Add AnchorWatchStateTest covering valid geometry, short-rode fallback
