fix(dashboard): include ANNOTATION_CREATED in hero resume query

findMostRecentDocumentIdByActor only matched TEXT_SAVED events, so documents
where the user drew annotation bounding boxes (but typed no transcription text)
were invisible to the hero resume card. Extending the IN clause to include
ANNOTATION_CREATED lets annotation-only work surface in the card (0% progress,
no excerpt — the correct state before transcription begins).
