Classic298 656a848043 perf: halve Redis round trips on model resolution and socket pools (#27225) ...

When WEBSOCKET_MANAGER=redis, app.state.MODELS and the socket session/
usage pools are Redis-backed dicts, so every membership test and
getitem is a network round trip:

- generate_chat_completion checked `model_id not in models` (HEXISTS)
  and then read `models[model_id]` (HGET) on every chat completion.
  A single .get() now serves both, with the same not-found error.
- The direct-connection branch spread the pool with `{**MODELS, ...}`,
  which iterates keys() then fetches each value — HKEYS plus one HGET
  per model. dict(MODELS.items()) issues a single HGETALL instead.
- get_user_ids_from_room called SESSION_POOL.get(sid) twice per
  session (once to filter, once for the value); the usage handler
  checked membership then fetched the same key. Both now do one
  lookup.

In non-Redis mode these are plain dicts and behavior is identical.
