Subject: [PATCH] feat: improve RustDesk template configuration (#571)

* feat: improve RustDesk template configuration

- Add comprehensive environment variables for RustDesk server
- Add RELAY_HOST, API_SERVER, ID_SERVER, and ENCRYPTION_KEY variables
- Follow Dokploy best practices (no container_name, proper port format)
- Use restart: unless-stopped policy
- Add encryption key generation with password helper

* fix: use explicit port mapping for RustDesk services

RustDesk requires explicit port bindings (host:container format) to function properly. The service uses specific ports for:
- 21115-21116 (TCP/UDP): hbbs service for ID and NAT traversal
- 21117-21119 (TCP): hbbr relay service

Without explicit port mapping, RustDesk clients cannot establish connections to the server.

This is an exception to Dokploy's general port guidelines due to RustDesk's specific networking requirements.
