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.
