feat(P4B.T2): WhiteboardPayload + shared whiteboards CRUD wrappers + tests
Adds WhiteboardPayload wire-format variant to MessagePayload/ParsedMessagePayload, creates the whiteboards.ts CRUD wrapper (createWhiteboard, listWhiteboardStrokes, insertWhiteboardStroke, clearWhiteboardStrokes), writes 5 unit tests (38/38 pass), re-exports from chat/index.ts, and registers conversation_whiteboards + whiteboard_strokes in packages/db-types so typecheck passes cleanly.
