wip(mechanic): inflight damage-flow + vendor scheme + PhotoAnnotate + TT views

Маркер «вот где остановилась mechanic-сессия» — не разбито по логическим коммитам,
зафиксировано целиком чтобы не потерять при отвлечении/чекаутах.

Modified:
- pages/InspectionEditor.tsx — расширение damage-flow внутри редактора
- pages/VehicleCard.tsx — vendor data + расширение карточки
- pages/InspectionReview.tsx — обновлённый review
- api/{auth,inspections,photos,vehicles}.ts — новые endpoints для TT + photo flow
- components/damage-flow/DamageClassifyDialog.tsx — multi-step UI
- components/vehicle-scheme/VendorVehicleScheme.tsx — SVG zone interaction
- data/damageVocabulary.ts — обновлённый словарь повреждений
- frontend index.html/manifest/icons — PWA-метаданные

New (untracked):
- components/damage-flow/PhotoAnnotateStep.tsx — новый шаг flow'а
- components/tt/ — vendor TT-state UI
- pages/TtStateDetail.tsx — экран осмотра вендора
- recon/findings/damage_model.md + damage_vocabulary.json + scheme/ — recon docs

Cleanup: удалены bash-garbage 'Last' и 'dict[str' из frontend/.
