feat(widget): editable task details, scrollable list, and overdue-task fixes

- Add description editing to the widget's task detail popup for
  doot/gtasks/trello, backed by new GET /api/widget/detail and
  POST /api/widget/update endpoints
- Make Google Tasks and Trello cards completable via the widget (Trello
  completion archives the card); fix Trello description never being
  fetched, which meant saving could silently wipe a card's real desc
- Fix google_tasks.due_date/updated_at (TEXT columns) never round-tripping
  through sql.NullTime, which broke cached Google Tasks reads whenever
  the cache was valid
- Fix native-task and Google-Task date-range queries excluding anything
  due before the window start, which dropped incomplete tasks off the
  widget the moment their due day passed (the "overdue tasks disappeared"
  bug)
- Fix native task description edits blanking the task's title
- Make the widget's day list scroll (LazyColumn) instead of clipping
- Optimistically remove a task from the widget immediately on completion,
  ahead of the authoritative background refresh
