feat(mcp): add MCP server with read-only tools for Coolify resources

Add Model Context Protocol server exposing Coolify infrastructure data
to AI assistants. Includes tools for listing/fetching servers, projects,
applications, databases, and services, scoped to authenticated team tokens.

- Add CoolifyServer with 10 read-only tools (list/get for all resource types)
- Add BuildsResponse and ResolvesTeam traits for shared tool logic
- Add EnsureMcpEnabled middleware guarding /mcp routes
- Add enable/disable MCP API endpoints (root-only)
- Add is_mcp_server_enabled toggle in instance settings and advanced UI
- Add migration for is_mcp_server_enabled column
- Add feature tests for MCP endpoints and toggle API
- Scrub sensitive keys (passwords, tokens, raw IDs) from all responses
