Add Learn tab; move quit to Safety; remove persistent MOB FAB

UI cleanup:
- Remove always-visible MOB FAB — Safety screen button is sufficient
- Remove floating quit button; move to bottom of Safety screen
- fragment_container is now clickable/focusable, blocking map touch-through
  for all overlays (trip reports, log, safety)
- Record Track FAB hidden while any overlay is shown, visible on map tab

New Learn tab (5th nav item):
- Migration guides for Navionics and Sea People (local markdown via DocFragment)
- ASA Course Catalog, ASA Online Learning, ColRegs, Sailing Flashcards
  (open in browser)
- Remove blanket assets/ .gitignore so markdown docs are tracked
