refactor(wear): wire wearable shell and integration tests

[Foxpace]

Connects the new wearable Compose features to the Android application, transport layer, theme, and integration tests.

What was added

• WearSensorBoxApp, dependency injection, manifest wiring, and WearTheme.
• Updated wearable message handling through the typed protocol.
• Emulator coverage for wearable-to-phone sync and Compose menu behavior.
• Policy-link tests and refreshed wearable strings and styles.
• Removal of the legacy DataSync and SensorTools helpers.

How it works

The wearable application initializes the Hilt graph and launches the Compose entry point. Protocol messages are decoded by the shared WearOsLib layer, domain use cases perform recording or synchronization, and instrumentation tests verify the device boundary and user-facing menu flow.
