dashboard: resolve employee names from directory/user, GE monogram photo fallback, kiosk sweep + label

- notifications shopfloor feed: resolve the employee name live when the stored
  value is a bare SSO (WJ notifications imported as SSOs, never converted), for
  both single and split-per-employee cards
- employee name resolver: after a directory miss, fall back to the shopdb User
  account (firstname/lastname, keyed by SSO username) so users from other
  locations still show a name
- shopfloor dashboard: employee photo falls back to the GE monogram (own asset,
  independent of the site_logo setting) with a loop-guarded onerror; recognition
  + recert tiles both covered
- shopfloor dashboard: 'All Business Units' filter label -> 'All Locations'
- geenforce display dispatcher: startup sweep also matches the imaging
  installers' 'GE Aerospace Dashboard/Lobby' shortcuts by name
