feat: enhance password-protected rooms with key commitments and management
- Add key commitment scheme for immediate password verification - Implement ownership transfer with /transfer command - Add password change functionality with /pass command - Include room metadata in initialization messages - Remove /help command and rename /changepass to /pass - Make room names tappable to show sidebar - Remove spaces in person/room counter display - Update UI to show lock icons and orange colors for protected rooms - Fix password verification to work with empty rooms - Add comprehensive tests for new functionality This update significantly improves the security and usability of password-protected rooms by allowing immediate verification without waiting for encrypted messages.
