feat(nav,settings): bottom nav 5+N collapsible menu + Indonesian locale

Background: 8 bottom-nav items squeeze long English labels on narrow
screens. 4.5.1 introduces the 5+N pattern: 5 main tabs plus a fixed
6th "More" button that pops a second-level menu (spring bounce) with
the remaining pages.

Changes:
- MainScreen: nav split into main (<=5, screenOrder-driven) + more
  (subMenuOrder); More button with popup panel + spring animation;
  BackHandler closes the menu before navigating back
- MoreMenuPopup: bottom-end card, current page highlighted, scrim
  click to dismiss
- UI Settings: page order card now has two zones (main menu, max 5,
  Settings locked last with no drag handle / more menu); move buttons
  between zones, drag-to-reorder within zones; new subMenuOrder pref
- Defaults: main = Satellites/Passes/Radar/Map/Settings,
  more = Mutual/Roaming/CwDecode; old screenOrder migrates by
  classifying pages against the default sub menu
- Hard-coded UI strings localized (Tracking/Lat/Lon/Qth/Connect/
  Track/Stop/CW permission prompts) into EN/ZH/TR
- NEW Indonesian locale (values-in, 181 strings + cw module strings)
  - user rule: every future release must update EN/ZH/TR/IN
- Version 4.5.1 (451)

Verified: check_strings.py OK (8 files, no bare apostrophes);
:app:compileDebugKotlin BUILD SUCCESSFUL locally.
