[Olasam-web]

Description

Update the existing subscriber logic to listen to messages from Redis Pub/Sub channels instead of polling the database.

Acceptance Criteria

2. Ensure proper handling of incoming messages, including deserialization and processing.
3. Validate that the subscriber correctly receives and processes messages from the Redis Pub/Sub channel.
