Implement full task inspector with subtasks, activity, and inline edit

Migration 041 adds parent_task_id to tasks for subtask hierarchy.
TaskDetailDialog now has three tabs: Overview (description, assignee,
project, goal, workspace, runs with error messages), Subtasks (child
tasks with status), and Activity (audit events and approval history).
Inline edit overlay covers title, description, assignee, risk, priority,
and parent task. Task delete is available from the dialog footer.
