feat(03-04): intake wizard UI — AIResultReview, ConfirmForm, IntakePage, router wiring

- AIResultReview: confidence meter (green/yellow/red), manufacturer/model/category/tags, editable name input, ai_notes card
- ConfirmForm: confirm/start-over action buttons with submitting spinner state
- AppShell: top-nav layout wrapper with HWLab logo and Inventory/Add Item nav links
- IntakePage: three-step wizard (upload → submitting → review) wired to submitIntake()
- router.tsx: lazy-loads IntakePage for /intake, Suspense+Spinner fallback
- Analyze button disabled during submitting (T-03-13 DoS mitigation)
