- Add Tiptap editor + toolbar and rich content rendering with sanitize-html
- Fix SSR hydration (immediatelyRender: false) and setContent options
- Comments: rich text + visibility selector, typed attachments (Id<_storage>)
- New Ticket: description rich text; attachments typed; queues typed
- Convex: server-side filters using indexes; priority order rename; stronger Doc/Id typing; remove helper with any
- Schemas/Mappers: zod v4 record typing; event payload record typing; customFields typed
- UI: replace any in header/play/list/timeline/fields; improve select typings
- Build passes; only non-blocking lint warnings remain
