Discover the active Wireless ADB port

[Avlaak]

Summary

Automatically discover the active Wireless ADB port when Wireless ADB is enabled and display it in the preference summary and switch dialog.

Implementation

• Discover _adb-tls-connect._tcp. services using Android NSD.
• Verify that resolved mDNS services belong to the local device.
• Fall back to a bounded local TCP scan of port 5555 and the dynamic range 33000–47000.
• Validate discovered ports using an ADB CNXN handshake.
• Release NSD listeners, sockets, coroutine jobs, and the Wi-Fi multicast lock with the preference lifecycle.
• Add English and Russian UI strings. Other locales retain the default fallback until Crowdin synchronization.

Testing

• ./gradlew :app:assembleDebug — passed.
• ./gradlew :app:testDebugUnitTest — no test sources.
• Android Lint reports no new feature-specific errors. Four unrelated pre-existing project errors remain.
