Bump applemusic, zotero, nextcloud MCP servers to latest

- applemusic-mcp: 0.15.1 -> 0.18.3 (adds keyring dep)
- zotero-mcp: 0.5.0 -> 0.9.1 (pyzotero 1.13.5, vendored pdf-inspector,
  updated dep set per pyproject)
- nextcloud-mcp-server: 0.121.3 -> 0.173.0 (adds anyio, uvicorn,
  cryptography, lxml, botocore, numpy, packaging, pypdfium2; updated
  postPatch for new uv_build/icalendar constraints)

All hashes computed via nix build on wilkes; nix flake check passes.
