fix(android): call-debug instrumentation for audio startup path

Browse Source 
Add emit_call_debug events at every step of the Android connect/audio
path so failures are visible in the Settings debug log without needing
adb logcat:

- connect:handshake_start/done/failed (with timing)
- connect:android_audio_preflight (wzp_native loaded + RECORD_AUDIO
  permission check via new has_record_audio_permission() JNI helper)
- connect:audio_stop_start/done
- connect:audio_mode_start/done/failed
- connect:audio_start_start/failed/panic/done (with oboe error code)
- connect:reuse_endpoint (endpoint reuse diagnostic)

Also adds has_record_audio_permission() to android_audio.rs — used in
the preflight event to confirm the OS has granted mic access before
wzp_oboe_start is called.

@@ -25,6 +25,8 @@ Working-tree diagnostic changes applied during this investigation:
- `crates/wzp-native/cpp/oboe_bridge.cpp`: return `-6` if both streams do not reach `Started` before the 2s poll deadline. This turns Oboe false-success into a visible Rust/JS error.
- `desktop/src/main.ts`: shared `connectWithTimeout()` for room joins and direct-call auto-connect; shared `errorMessage()` for useful toast text.
- `desktop/src-tauri/src/engine.rs`: emit `connect:handshake_*`, `connect:android_audio_preflight`, `connect:audio_*` markers around each Android-only join step.
- `desktop/src-tauri/src/lib.rs`: emit `connect:reuse_endpoint` so we can see whether the room join is sharing the signal QUIC endpoint.
