beatzaplentyandClaude Sonnet 4.6 b8d21d78d9 fix: wire vars.nfsShares.options and correct stale share key names
- Filter non-attrset values from nfsShares in server.nix so the
  poolDatasets loop skips the new `options` string entry
- Fix typo proxomoxLxcImages → proxmoxLxcImages in server.nix exports
- Rename proxmoxPxeImages → pxebootImages in mount-pxe-images.nix and
  pxe-boot.nix to match the actual key in variables.nix
