Uninstall: drop database & user, clean up Caddy configs, cert removal

- Panel uninstall reads .env to find DB driver/name/user
- Prompts to drop MySQL/MariaDB/PostgreSQL database and user
- Falls back gracefully if DB client not found or root auth fails
- Cleans up Caddy config blocks for panel and wings
- Wings uninstall offers to remove Let's Encrypt certs
- Better web server restart after removing configs
