feat(mcp): add 8 new validated MCP servers

Add actual-mcp, beszel-mcp, gitea-mcp, ha-mcp, limesurvey-mcp,
linkwarden-mcp, mcp-grafana, and superset-mcp with full validation.

Key fixes applied:
- linkwarden-mcp: Added 'stdio' subcommand to ENTRYPOINT
- mcp-grafana: Fixed build path (./cmd/mcp-grafana) and added '--transport stdio' flag

All 8 servers validated with MCP protocol handshake.
Working MCP server count: 24 (up from 16)
