Major refactor: Fix SQLite concurrency, remove rate limiting, simplify architecture

- Switch to single Gunicorn worker to eliminate SQLite database locking issues
- Remove Flask-Limiter and all rate limiting complexity
- Remove Cloudflare proxy setup and dependencies
- Simplify configuration and remove unnecessary features
- Update all templates and static files for streamlined operation
- Clean up old files and documentation
- Restore stable database from backup
- System now runs fast and reliably without database locks
