feat(admin/trips): surface dumpsite release records in trip detail panel

- Eager-load dumpsiteReleases.dumpsite + dumpsiteReleases.releasedByDriver
  in AdminTripController::show()
- Add releases[] array to TripResource via whenLoaded('dumpsiteReleases')
  - Fields: weight_kg, released_at, dumpsite_name, driver_name,
    gate_pass_number, dumpsite_attendant, notes
- Admin Trips detail panel now shows a 'Dumpsite Releases' section
  below the timeline with per-release cards
- Load row updated to show release count e.g. '450 kg (2 releases)'
