chore(logout): add targeted logging for deep-link diagnostics

Add strategic logging to diagnose logout deep-link issues without
impacting performance. Logs focus on key events only:
- Logout initiation and browser launch
- Deep-link reception and URI matching
- Callback invocation and completion

Removed excessive polling logs that were causing timeouts during
login flow due to performance degradation.
