Simplify configurator to essential config options

Reduced TUI menu to 10 core options:
1. Bot Settings
2. Connection
3. LLM Backend
4. Response Settings
5. Channels
6. History & Memory
7. Rate Limits
8. Web Status Page
9. Announcements
10. Setup Wizard

Added fq51BBS-style save/restart options:
- 11. Save (stay in menu)
- 12. Save & Restart Bot (apply changes now)
- 13. Save & Exit (save, restart, exit)
- 14. Exit without Saving

Removed from UI (still in code for future use):
- Safety & Filtering
- User Management
- Commands/Custom Commands
- Personality/Personas
- Logging
- Webhooks

Simplified default config and example config to match.
