refactor: remove explicit any across admin forms and catalog actions

- Type resolveAsChild generically over Base UI render-prop type
- Type catalog/rooms/catalog-items Prisma updates with Prisma.*UpdateInput
- Type EventForm/PollForm with explicit form-value interfaces
- Type EventPrizesManager/PollQuestionsManager with validator input types
- All typecheck, lint, and 312 tests pass
