Wire up SortableJS in app.js to enable dragging task cards between
Kanban columns. On drop, fires htmx PUT requests to the appropriate
Board handler (Start/Pause/Resume/Complete) based on the column
transition. Invalid transitions are reverted. Sortable instances are
destroyed and recreated after htmx swaps to prevent memory leaks.
Also centralizes detail panel open/close/edit helpers and Escape key
handling.

Server-rendered Kanban board with 4 status columns (Pending, Active,
Paused, Completed), task cards with category colors and elapsed time,
filter bar with category chips and subtask toggle, and inline create
task form. All handlers support htmx partial updates for status
transitions (start, pause, resume, complete, abandon, create).
