Kanban Board View

Cases mapped to a procedure can now be viewed as a kanban board (currently behind a feature flag), with one procedure visible at a time and a column per stage. Cards only appear once a case has picked up a stage from the selected procedure; custom stages outside the procedure don’t show up on the board. Filters carry over when switching between list and board view, and assignees can be edited directly from a card.

The board updates live as changes land in other tabs, and clicking a card opens the full procedure with that stage highlighted. Moving cards between columns isn’t supported yet — stage transitions carry logic that a drag-and-drop move can’t safely replicate — but rewind, rerun, and skip are on the roadmap.
