perf: speed up deploy-android via MobSF pre-warm and parallel integration tests

Start MobSF as a dep of build-android (_mobsf-start) so it warms up during
the APK build instead of blocking afterwards (saves up to 90 s). Add
_integrations task to run integration and integration-ui in parallel since
they use random Stalwart ports and different Flutter build targets.

Also add `docker rm ... || true` before `docker run` in both _mobsf-start and
mobsf_scan.sh to handle stopped-but-not-removed containers gracefully.

 ## Tasks
 
+## Speed up `task deploy-android`
+
+Two parallelism improvements:
+
+- `_integrations` internal task: runs `integration` and `integration-ui` in parallel (they use
+  random Stalwart ports and different Flutter build targets so there is no conflict).
+- `_mobsf-start` internal task: starts the MobSF Docker container as a dep of `build-android`,
+  so it warms up concurrently with the APK build instead of blocking for up to 90 s afterwards.
+- `scripts/mobsf_scan.sh`: added `docker rm $CONTAINER_NAME 2>/dev/null || true` before
+  `docker run` to handle stopped-but-not-yet-removed containers (same fix applied to the new
+  `_mobsf-start` task).

 ## Android E2E test verifies APK before deploy
