fix(android): improve exact alarm permission check with fallback strategies

Fix reflection-based permission check that was failing with NoSuchMethodException.
Add multiple fallback strategies to ensure permission check works reliably.

Changes:
- Add getDeclaredMethod() fallback when getMethod() fails
- Add heuristic fallback: if exact alarms not allowed, assume they can be requested
- Improve error handling: catch NoSuchMethodException separately from other exceptions
- Add debug logging to track which reflection path is taken
- Change reflection failure log level from ERROR to WARNING (we have fallback)

The heuristic fallback is safe because:
- If exact alarms are not currently allowed, we should try to request them
- Only edge case is permanently denied (rare), worst case is unnecessary Settings redirect
- Better than failing silently or blocking permission requests

Fixes reflection failures seen in logcat where Settings.canRequestScheduleExactAlarms()
method lookup was failing, causing unnecessary Settings redirects.
