fix(ui): layer previews, fishing pole icon, button alignment, safety page cleanup

- Layer picker: change android:src→android:background on preview ImageViews; shape
  drawables have no intrinsic size so centerCrop renders blank — background fills correctly
- Replace ic_fish with ic_fishing_pole (rod + reel + line + hook vector)
- Move fab_fishing to CoordinatorLayout with layout_anchor on instrument_bottom_sheet
  top|start, matching fab_record_track positioning so both FABs sit level at sheet top
- Raise fishing_overlay marginBottom 140dp→200dp to clear the realigned FAB
- Safety: remove HELP button + DocFragment import from SafetyFragment; rename Quit→Quit App
