Teknium 4093201c47 feat(kanban): dashboard plugin — Linear/Fusion-style board UI
Ships plugins/kanban/dashboard/ as a bundled dashboard plugin. No core
changes — uses the standard dashboard plugin contract (manifest.json +
dist/index.js + plugin_api.py) documented in 'Extending the Dashboard'.

What the tab gives you:
- One column per kanban status (todo / ready / running / blocked / done;
  archived behind a toggle), column counts, coloured status dots.
- Cards with id, title, priority badge, tenant tag, assignee,
  comment/link counts, 'created N ago'.
- HTML5 drag-drop between columns — status change routes through the
  same kanban_db code the CLI /kanban verbs use, so the three surfaces
  (CLI, gateway, dashboard) can never drift.
- Inline create per-column (title, assignee, priority).
- Side drawer on card click: description, status action row
  (→ ready / → running / block / unblock / complete / archive),
  dependency links, comment thread with Enter-to-submit,
  last 20 events.
- Toolbar: search, tenant filter, assignee filter, show-archived,
  nudge-dispatcher (skip the 60s wait), refresh.
- Live updates via WebSocket tailing task_events — the board reflects
  CLI or gateway actions in real time.

REST surface under /api/plugins/kanban/: GET /board, GET /tasks/:id,
POST /tasks, PATCH /tasks/:id, POST /tasks/:id/comments, POST /links,
DELETE /links, POST /dispatch, WS /events. Every handler is a thin
wrapper around kanban_db — no new business logic.

Visually theme-aware: the plugin CSS reads only --color-*, --radius,
--font-mono etc. so it reskins with whichever dashboard theme is active.

Tests (tests/plugins/test_kanban_dashboard_plugin.py, 16 tests):
- empty board shape
- create + appears in ready column with tenant/assignee rollups
- tenant filter
- detail includes parents/children/events
- 404 on unknown task
- PATCH status: complete / block / unblock / ready drag-drop / running
- PATCH reassign, priority, edit, invalid-status rejection
- POST comment (plus empty-body rejection)
- POST link + DELETE link + cycle rejection
- POST dispatch (dry run)

All 76 kanban tests pass under scripts/run_tests.sh.

Docs: website/docs/user-guide/features/kanban.md gains a full
'Dashboard (GUI)' section covering install, architecture, REST surface,
live-updates mechanism, extending, and scope boundary.

"""Tests for the Kanban dashboard plugin backend (plugins/kanban/dashboard/plugin_api.py).
The plugin mounts as /api/plugins/kanban/ inside the dashboard's FastAPI app,
but here we attach its router to a bare FastAPI instance so we can test the
REST surface without spinning up the whole dashboard.
