fix: persist Proxmox settings via localStorage; fix Remotes add/refresh flow

- ProxmoxSettings: load all six settings from localStorage on mount via
  useEffect, wire Save button to write values and show a 2s confirmation,
  wire Reset button to clear keys and restore defaults
- RemotesPage: attach loadRemotes() to the header Refresh button onClick
  and replace the no-op onRefresh prop passed to RemotesList
- EditRemoteForm: add password field to RemoteConfig interface and form
  so handleEditRemote receives a complete config; use DialogFooter for
  consistent button layout
