catalog(kanban-gantt): pin 1.3.1 (74c38ce) — live updates without a Refresh button

Re-pins the entry to the 1.3.1 release: the page follows a websocket push (an out-of-UI write reaches it in ~1s with zero /gantt polls), a board missing on the active gateway falls back instead of answering 503 forever, and the plugin's board paths are asserted against the pinned HERMES_KANBAN_DB trap. Screenshot URLs follow the same pin.
