- Fix Prisma type mismatches (OR filter, Person.companyId, Estimate.projectId, Ticket.createdAt)
- Fix webhook PATCH route (moved to [id]/route.ts)
- Fix mobile-bottom-nav type safety
- Fix KB route where-clause type
- Fix test-mail banner null vs undefined
- Fix task comment fetch: add cancellation + error toast
