v1.25: Add automatic update system with GitHub integration

Implements a complete update system similar to the kiosk project:
- Check GitHub for latest releases via API
- Display current vs latest version comparison
- Show breaking changes warning with changelog link
- Create automatic timestamped backups of script and configs
- Display clear rollback instructions before updating
- Download and install new version safely
- Offer to restart Asterisk, Baresip, and COTURN services
- New "Check for Updates" option in Tools menu

Features:
- Version constants and GitHub repo info
- check_for_updates() - fetches and compares versions
- perform_update() - handles backup, download, and installation
- restart_all_services() - safely restarts all services
- Fallback to git clone if direct download unavailable
- Rate limit detection and error handling
