Endpoints for retrieving the current user's assignments, including active assignments split by priority, completed assignments, and due assignments filtered by time scope.
Each assignment includes its content, type, bucket, parent, assignees, due dates, completion status, and any child assignments (e.g. card steps nested under their parent card).
Note: These endpoints return the full result set and are not paginated.
Endpoints:
GET /my/assignments.jsonwill return the current user's active assignments grouped intoprioritiesandnon_priorities. Card table steps are normalized to their parent card, with steps included aschildren.
