LLC Kanban boards missing from UI — boards API (list/create/move) exists but no frontend board view #12213

Summary

The LLC Kanban board is missing from the UI. The backend board API is fully implemented, but there is no Kanban/board view in the frontend, so the board feature is unreachable for users.

Evidence

• Backend present and working (llc/api/boards.py, prefix /api/llc/boards):
  • GET /api/llc/boards (list) — returns 200 [] for a company with no boards
  • POST /api/llc/boards/kanban (create kanban board)
  • POST /api/llc/boards/sprint
  • GET /api/llc/boards/{id} · GET /api/llc/boards/{id}/items · POST /api/llc/boards/{id}/move
• Frontend: no Kanban/board view found. find autobot-frontend/src autobot-slm-frontend/src -iname '*kanban*' -o -iname '*board*' returns only unrelated dashboards (FailureAnalysis, Experiment, SLO, Grafana) — no LLC board component.

Impact

Users cannot see or manage work items on a board (no visual backlog/kanban/sprint board), even though the API to create boards and move items exists. Unwired feature.

Request

Add the Kanban (and sprint) board view to the LLC company UI, wired to /api/llc/boards (create board, list items by column, POST /{id}/move for drag-and-drop).
