Subject: [PATCH] feat: multi-server switcher + fleet context

- WithFleetContext concern: resolves the active server (session, default first
  online) + the fleet.
- ServerSwitcher Livewire component in the persistent sidebar: dropdown of the
  fleet; selecting persists active_server_id in the session and re-navigates so
  panels reflect the choice.
- Dashboard reacts: resource rings + panel subtitles follow the active server.
