chore(android): Update targetSdk to API 36 (Android 16) (#5016)

* ref(android): Update targetSdk to API 36 (Android 16)

Updates targetSdk and compileSdk to API Level 36 for Android 16 support.

Breaking changes addressed:
- Created ThreadUtil helper for version-aware thread ID retrieval
- Migrated from deprecated Thread.getId() to Thread.threadId() with backward compatibility
- Updated sample app to use OnBackPressedCallback instead of deprecated onBackPressed()

The scheduleAtFixedRate behavior change is acceptable for our performance collection use case.
