Stage 3 — WO photos + ETA + QR + public tracking page

- HasMedia (Spatie) on WorkOrder with `photos` collection
- eta_at + tracking_token columns; token auto-generated on create
- Public /t/{token} page — tenant-scoped via subdomain, white-label themed
- QR code SVG via chillerlan/php-qrcode (inline modal + download)
- Filament: SpatieMediaLibraryFileUpload + ETA picker + tracking section
- EditWorkOrder header action "Link client (QR)" modal
- Fix: Auditable::dontSubmitEmptyLogs() → dontLogEmptyChanges() (removed in activitylog)
- Tests: TrackingPageTest (4 pass) covering token gen + cross-tenant isolation
