Fix post ownership detection for local posts to enable edit functionality

- Fixed ownership detection logic to handle both local and federated post formats
- Local posts have acct="username" while federated posts have acct="username@instance.com"
- Updated logic in both timeline_view.py and post_actions_manager.py for consistency
- Removed duplicate keyboard shortcut from context menu to prevent conflicts
- Added debug logging to help troubleshoot ownership detection
- Edit functionality now works correctly for user's own posts
