Closes out the Android terminal plan (Phases A → F).
- MainActivity:
* Immersive mode via WindowInsetsControllerCompat — hides status +
navigation bars, swipe-to-reveal with auto-hide
(BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE). Re-applied in onResume so
a transient overlay can't leave the bars visible.
* Lock Task Mode — startLockTask() in onResume. The manifest already
declares lockTaskMode="if_whitelisted", so this enters kiosk on a
properly MDM-provisioned tablet and is a silent no-op (caught
SecurityException) on dev / unprovisioned devices.
- TerminalScreen:
* SnackbarHost pinned at the bottom; LaunchedEffect(actionResult)
shows "Queued — will sync when back online" whenever an offline
action gets queued, so the cashier has explicit feedback beyond the
top-bar pending pill.
* 4 new locale strings (en/fr/de/lb) for the snackbar copy.
- Manifest cleanup: dropped redundant tools:replace from the debug
AndroidManifest overlay (networkSecurityConfig isn't set in the main
manifest, so the replace directive was a no-op + emitted a warning).
Skipped from the plan: a custom splash screen (the existing theme
background renders for the cold-start frame; adding the splashscreen
library is polish for a follow-up) and per-action success toasts
(the action sheet closing + balance refresh + recent-feed update are
adequate confirmation).
Verified by ./gradlew assembleDebug — clean build.

Two small dev-quality fixes shaken out by manual testing:
- Add a debug-only network_security_config.xml that whitelists 10.0.2.2,
localhost and 127.0.0.1 for cleartext HTTP. Without this, the dev
emulator can't reach the Python dev server because targetSdk 35
forbids cleartext HTTP by default. Lives under app/src/debug/ so it
ships only in debug APKs — release builds keep the platform default
(no cleartext at all).
- TerminalViewModel.runAction now extracts the JSON {message: ...} field
from HttpException response bodies instead of just showing "HTTP 400".
Cashiers (and developers) now see "Staff PIN is required for this
operation" / "Daily stamp limit of N reached" inline in the failed
action sheet, surfacing the same business-error text the server
already returns.
