test(ci): share APKs between jobs and expand smoke tests

CI — build job now uploads both APKs as the 'test-apks' artifact.
smoke-test job downloads them and passes -x assembleDebug
-x assembleDebugAndroidTest to skip recompilation (~4 min saved).
Test results uploaded as 'smoke-test-results' artifact on every run.

Smoke tests expanded from 1 → 11 tests covering:
  - MainActivity launches without crash
  - All 4 bottom-nav tabs are displayed
  - Safety tab: Safety Dashboard, ACTIVATE MOB, ANCHOR WATCH visible
  - Log tab: voice-log mic FAB visible
  - Instruments tab: bottom sheet displayed
  - Map tab: returns from overlay, mapView visible
  - MOB FAB: always visible, visible on Safety tab
  - Record Track FAB: displayed, toggles to Stop Recording, toggles back

MainActivity: moved isRecording observer to initializeUI() so the
FAB content description updates without requiring GPS permission
(needed for emulator tests that run without location permission).
