* feat: add Mumble voice chat server template

- Add Mumble VoIP server blueprint with docker-compose.yml
- Configure environment variables for superuser password, welcome text, and max users
- Add template.toml with auto-generated secure password
- Follow Dokploy best practices (no container_name, proper port format)
- Add Mumble metadata to meta.json with proper tags
- Support for TCP and UDP on port 64738

* Update template.toml

* fix: correct JSON formatting in meta.json for Mumble template entry
