🔧(compose) share the backend redis with the summary stack

The summary settings already default to the `redis` host, so
`redis-summary` was unused. Remove it and depend on `redis`.

Pin the summary Celery and task tracker URLs to DB 2 in
`summary.dist` to isolate them from LiveKit and the backend
Celery broker (DB 0) and the Django cache (DB 1).

-### LiveKit agents (optional)
-
-The LiveKit agents are not started by `make run`. Each one runs its own
-container and stays connected to LiveKit, which costs CPU and memory you
-don't need unless you work on the features they power. Start them only
-when you need them.
-
-| Agent | Feature | Make command | Setting in `env.d/development/common` |
-|---|---|---|---|
-| `metadata-collector-dev` | Recording metadata (used to identify speakers in transcripts) | `make run-agent-metadata-collector` | `METADATA_COLLECTOR_ENABLED=True` |
-| `multi-user-transcriber-dev` | Live subtitles | `make run-agent-multi-user-transcriber` | `ROOM_SUBTITLE_ENABLED=True` |
-
-To start both at once:
-```shellscript
-$ make run-agents
-```
-
-Then set the matching settings to `True` and restart the backend so it
-picks them up:
-```shellscript
-$ make run-backend
-```
-
-The multi-user transcriber also needs a speech-to-text provider. Configure
-`STT_PROVIDER` and its credentials in
-`env.d/development/multi_user_transcriber`.
-
-Keep the settings and the agents in sync: if a setting is `True` while its
-agent is stopped, the backend still dispatches jobs to it and the feature
-fails silently.
