Migrate the old revision keys before deployment.

Commit c8aa0a7 changes the namespace from tryna:recommendation:latest-revision to recommendation:latest-revision. The ECS deployment does not migrate Valkey keys. If old keys remain, ensure_current reads no value and allows stale requests to proceed. Migrate the old keys or add a time-bounded fallback read.

In `@app/services/recommendation/revision_guard_service.py` at line 12, Update the
revision lookup used by ensure_current to handle the legacy
tryna:recommendation:latest-revision key during deployment, either by migrating
that key to the recommendation:latest-revision namespace or by adding a
time-bounded fallback read. Preserve the current namespace as the primary key
and ensure existing legacy values still enforce revision checks.
