android: fix voice permissions, theme apply, and profile avatar layout

android/CHANGELOG.md

@@ -429,3 +429,11 @@
 - Added accessibility refinements for key surfaces and controls:
   - explicit content descriptions for avatars and tab-like controls,
   - voice record button semantic label for TalkBack.
+
+### Step 69 - Bugfix pass: voice recording, theme apply, profile avatar UX
+- Fixed voice recording start on Android by switching `VoiceRecorder` to compatible `MediaRecorder()` initialization.
+- Fixed microphone permission flow: record action now triggers runtime permission request reliably and auto-starts recording after grant.
+- Fixed theme switching application by introducing app-level `MessengerTheme` and switching app manifest base theme to DayNight.
+- Fixed profile screen usability after avatar upload:
+  - enabled vertical scrolling with safe insets/navigation padding,
+  - constrained avatar preview to a centered circular area instead of full-screen takeover.
