feat: wire Zod validation into API routes, improve types and components

- Add 8 new Zod schemas (UpdateCustomer, UpdateSupplier, UpdateSupplierInvoice,
  UpdateAccount, BankUnlink, RunReconciliation, CorrectJournalEntry,
  EvaluateMappingRules) and wire validateBody() into 24 JSON-body API routes
- Remove redundant manual validation checks replaced by Zod
- Add comprehensive schema tests (222 tests)
- Improve type definitions in types/index.ts with expanded interfaces
- Refactor extension types (push-notifications, receipt-ocr) for cleaner imports
- Update transaction components (BatchCategorySelector, SwipeCategorizationView,
  QuickReviewDialog, VatTreatmentSelect) and invoice inbox workspace
- Add invoice-inbox utilities and type decoupling tests
- Fix NE-bilaga, SRU export, and invoice PDF template type usage
- Update CLAUDE.md with expanded architecture documentation
