feat(injector-protocols): full module — resource + PDF export via Browsershot

Implements the injector diagnostic protocol module per spec:
- Migration: injector_protocols + injector_protocol_rows with company_id
  (multi-tenant), vehicle_id (not car_id — this CRM uses Vehicle),
  master_id FK to users, snapshot fields (car_model/plate/vin/mileage/year/
  injector_brand) captured at protocol time.
- Models with BelongsToTenant; auto-generate protocol_number as
  PS-{tenantId}-{year}-{seq6}; auto-seed 8 empty rows on create.
- Permissions: injector_protocols.view + injector_protocols.conclude.
  Default roles: owner/admin (both), manager (both), receptionist (view
  only), mechanic (both). Test permission count updated 52→54.
- InjectorProtocolResource under Service nav group with 4 sections:
  data auto+client (with client_id/vehicle_id lookups auto-filling
  snapshot fields), reason checkboxes, 8-row repeater for measurements
  (Repeater with position hidden; fixed 8, non-addable/deletable),
  conclusion + comment + master signature.
- Table with columns, badge filters, PDF action.
- Blade PDF template: pixel-close to reference (graphite/gold/blue
  brand tokens, striped rows, rotated 'ФОРСУНКИ' header).
- Route /app/injector-protocols/{id}/pdf with permission gate,
  streams PDF via new InjectorProtocolPdfService (Browsershot).
- Dockerfile: install nodejs 22 + chromium + noto fonts + puppeteer-core
  in /opt/browsershot; env vars for Browsershot binary paths.
- +71 RU/EN translations covering resource + PDF template.

All 306 tests pass.
