feat: realtime WebSocket layer for live events and streaming logs

- Backend: ConnectionManager, Redis-backed bus with in-process fallback,
  channel authorization, and typed emit helpers wired into workers
  (ai_runtime, sandbox_gateway), workforce/sandbox/billing/audit/error services.
- Frontend: single shared WS client with backoff + heartbeat, RealtimeProvider,
  useLiveChannel/useLiveEvent hooks, live indicators on task detail, manager
  chat, dashboard, traces, sandbox terminal, admin errors, and billing.
- Contracts: WsEvent/WsServerFrame/WsClientFrame types mirroring the port.

All 255 backend tests pass; web typecheck and build pass.

+"""Realtime push contract: the event envelope and the typed publishers.
+
+This module is an **application port**. Services depend on it; the WebSocket
+adapter in ``app.interfaces.realtime`` implements it. That direction matters:
+the run engine must be able to publish without knowing that a browser exists,
+and a worker process that never serves a socket still publishes the same way.
+
+Two parts:
+
+* **The envelope** (:class:`RealtimeEvent`) and the channel naming scheme.
+  Framework-free, like every other port.
+* **The typed publishers** — ``emit_run_step`` and friends. They own the
+  fan-out channels and the one rule that makes live feeds safe to call from
+  anywhere: *publishing never raises*. A feed must not be able to fail a task
+  run, a sandbox command or a billing write.
+
+The publisher is process-wide state, set once by a composition root
+(``app.main`` for the API, ``app.workers.__main__`` for the workers). Until
+then it is a :class:`NullPublisher` — publishing is a no-op rather than a
+missing-import crash.

+2. **Redis pub/sub.** Carries events published by *other* processes: the

+* The relay task owns the subscription lifecycle; it starts with the app and
+  stops on shutdown, and reconnects on its own after a broker restart.

+
+The token travels as a query parameter because the browser WebSocket API cannot
+set an ``Authorization`` header. That is a deliberate, contained exception to
+the header-only rule: the token is short-lived, the socket is TLS-terminated in
+any real deployment, and the alternative (a cookie) would drag CSRF into a
+protocol that has no CSRF story.
+
+Protocol — small, symmetric, JSON in both directions:
+
+.. code-block:: text
+
+    client -> {"action": "subscribe",   "channels": ["org:…", "task:…"]}
+    client -> {"action": "unsubscribe", "channels": ["task:…"]}

+    server -> {"type": "pong"}
+    server -> {"type": "error",      "message": "…"}
+
+A rejected channel is reported, not hidden: "my task page is not live" must be
+answerable from the browser console alone.

+Authorization queries open their own short-lived session: a socket can stay
+open for hours, and one SQLAlchemy session per open tab would quietly exhaust
+the connection pool.
