ui: runner management dashboard (view/manage distributed workers) — backlog/low-priority

[AlbinoGeek]

Summary

A UI to view and manage distributed-worker runners — roster/status, heartbeats, and queue activity — plus administration of runner access (approve / revoke).

Context

Requested by @gissf1 in #31:

we should at some point have a UI to view and manage runners, but that would need authentication and login permissions and a bunch of other stuff, so if there's no ticket for it yet, create one, but it should be in the backlog and low priority at this time.

Scope (provisional)

• View — live runner roster (ACTIVE / IDLE / DEAD), last heartbeat, current claim, host/identity; queue depth and in-flight runs.
• Manage — approve / revoke a runner (ties into the submission whitelist → OAuth path from api: HTTP queue API, runner registration, and submission auth for distributed worker mode #31), pause / drain a runner, inspect or re-queue jobs.
• Requires — an authentication + login/permissions layer; depends on the queue API + auth surface from api: HTTP queue API, runner registration, and submission auth for distributed worker mode #31.

Priority

Backlog / low priority (per @gissf1). Not on the critical path. Depends on #31 (HTTP queue API + runner registration + submission auth) landing first.
