* fix(web): close kanban preview when opening the edit dialog
The dialog overlay used to mask the preview panel behind a backdrop blur;
once the blur was dropped in #761, the preview kept rendering alongside
the dialog and the layout looked broken — especially noticeable when
editing a backlog task whose preview was already pinned open.
* fix(web): stop card-click from firing when using kanban dropdown
React's synthetic events bubble through the React tree even from a portal,
so clicking Archive or Delete in the kanban card's dropdown propagated up
to the card's onClick and navigated to the task page instead of opening
the confirm dialog. Stop click propagation on each menu item and stabilize
the new edit-handler's useCallback dep (PR review feedback).
* fix(web): condense kanban handler comments to one line
