Added proper ordering configuration (separate: true and order clause)
to subtask queries in query-builders.js. This ensures subtasks are
always returned in the correct order based on the 'order' field and
'created_at' timestamp, preventing the intermittent reordering bug
that occurred after checking subtasks as complete and reloading.
Fixes#921
* Add projects with due dates to upcoming view
Fetch and include projects with due_date_at in the upcoming range
when type=upcoming is requested. Projects are filtered by ownership
or permissions and exclude completed/archived projects.
Part of #925
* Display upcoming projects in Upcoming view
Add UI to show projects with due dates in the Upcoming view.
Projects are displayed in a separate section below tasks with
links to project details and formatted due dates.
Fixes#925
* Fix prettier formatting errors
