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

+Read-only MCP server for Coolify, scoped to the authenticated team token.
+
+Recommended workflow:
+1. get_infrastructure_overview — start here; single call returns all servers, projects with resource counts, and aggregates.
+2. list_servers / list_projects / list_applications / list_databases / list_services — paginated summary listings (default 50 per page, cap 100).
+3. get_server / get_application / get_database / get_service — full details for a single UUID.
+
+Every response is `{ data, _actions?, _pagination? }`. `_actions` suggests the next tool + args; `_pagination.next` is the args to call again for the next page.
