feat(FN-3365): pass workspace verification gates in board component

Fix FN-3365 completes Step 3 of workspace verification gates by making a minor adjustment to the Board component in the dashboard, likely correcting a validation or boundary condition that was previously failing.

Missing or invalid priority values normalize to `normal`.

 - Task detail surface is shared through `TaskDetailContent` (exported from `TaskDetailModal.tsx`): desktop/tablet `ListView` renders it inline in the split right pane, while mobile and non-list entry points continue using `TaskDetailModal`.
 - In desktop split mode, `ListView` now uses a compact sidebar-first control layout (count/actions/summary chips + collapsible "View options" panel) to keep list controls dense alongside the inline detail pane; mobile keeps the card-first flow with a toolbar "View options" entry point for the same visibility/filter toggles.

 Board ordering behavior:
-- Active work columns (`triage`, `todo`, `in-progress`, `in-review`) remain priority-ordered.
+- `todo` mirrors scheduler dispatch order: priority first (`urgent` → `low`), then oldest `createdAt` within a priority tier, then task ID as deterministic tie-break.
+- `triage`, `in-progress`, and `in-review` remain priority-first with task-ID tie-breaks (`in-review` still pins merge-active statuses above non-merging tasks).
 - The `done` column is recency-ordered by completion time (newest first), using `columnMovedAt` as primary and falling back to `updatedAt` then `createdAt` for legacy tasks.
