feat(mobile): keep team, template, and report flows in sync with the server

Team, meeting, memo, template, command, and dictionary screens drifted from
the server contract, and report submission could hang instead of confirming
to the user. The screens now use the server responses directly.

The retired Expo shell is removed; the React Native app is the mobile client.
Gradle-generated vector-icon drawables are ignored rather than committed.
