fix: loading screen via Go handler instead of file:// HTML

Browse Source 
- bee-web.service: remove After=bee-audit so Go starts immediately
- Go serves loading page from / when audit JSON not yet present;
  JS polls /api/ready (503 until file exists, 200 when ready)
  then redirects to dashboard
- bee-openbox-session: wait for /healthz (Go binds fast <2s),
  open http://localhost/ directly — no file:// cross-origin issues
- Remove loading.html static file
