feat(orchestrator): tasks tab with register, inbox and queue

Add a Tasks tab that lists the kvb-org-rasci register next to the inbox
and the heavy-job queue, in list, board and RASCI matrix views, each
task with its roles, WSJF, open work and the merge flow of its worktree.

- Task priority pins and WSJF estimates are signed with the operator's
  passkey and applied by the runner through rasci.py; the hub verifies
  the signature itself before it queues a job or logs the change, the
  runner verifies it again and runs only the checked argv, from /, with
  a pinned PATH and a 30 s process-group limit.
- The runner refuses task changes into a council that is a symlink, not
  owned by its uid or given by a relative path, and while the installed
  council.py, nofollow.py or rasci.py differ from the tree.
- Only tasks the hub can sign whole are editable (task slug and length).
- Page lookups keyed by register text use Object.hasOwn, so a status or
  party named like an Object.prototype member cannot break the views.
- The inbox screen renders through the tasks screen, so its task filter
  shows with "Wartet auf Operator" pressed.

Tests: 604 unit tests OK, e2e 15/15 OK (Chromium and Firefox).
