Subject: [PATCH] fix(api): remove duplicate to_dict() call in /api/graph/tasks

TaskManager.list_tasks() already returns a list of dicts (it calls
t.to_dict() internally at task.py:170). The endpoint then called
.to_dict() again on these plain dicts, raising AttributeError on
every request to GET /api/graph/tasks.
