Fix flake.lock bump host eval failures (MCP command type + Jellyfin 10.11.11 hash)

[Copilot]

The scheduled flake.lock bump failed in check-hosts after dependency updates changed evaluation behavior for two hosts. This PR applies the smallest scoped config updates needed to restore host evaluation on the lock-bump branch.

• Home Manager MCP config typing (redo-2)

  • programs.mcp.servers.aws-support-mcp-server.command now passes a string path, matching the module type (null or string) expected by Home Manager.

• nixarr Jellyfin OpenAPI hash compatibility (romeo-2)

  • Extended the temporary python-deps.nix patch injection to include Jellyfin 10.11.11, resolving the missing-version hash lookup introduced by the lock update.

• Targeted diff only

  • Changes are limited to:
    • home-manager/bcnelson/_mixins/mcp/aws/support.nix
    • nixos/romeo/nixarr.nix

# before
command = awsSupportLauncher;

# after
command = "${awsSupportLauncher}";
