fix(mcp): resolve proxmox-mcp fastmcp import, mark snipeit-mcp blocked

- proxmox-mcp: Fixed by patching pyproject.toml to use fastmcp from PyPI
  and updating imports from mcp.server.fastmcp to fastmcp. Container now
  builds and runs (requires PROXMOX_MCP_CONFIG env var).
- snipeit-mcp: Created stub Dockerfile that exits with error message.
  Upstream depends on private snipeit-api package never published to PyPI.
- STATUS.md: Updated to reflect 25 working MCP servers including proxmox-mcp.
- .env: Added template with placeholders for required credentials.
