Pull request overview

Adds a new “Activity Aggregator” feature to the LMS service, exposing an API endpoint that routes activity consumption updates to a dedicated Pekko actor/module (with Redis-backed graph reads + optional dedup + Cassandra updates).

Changes:

• Introduces new activity-aggregator Maven module with actor/util/domain code and tests.
• Wires the new actor into the Play service (dependency, actor binding, router deployment config, and a new /v1/activity/agg route/controller + request validator).
• Updates existing consumption flow to optionally route events to the new Activity Aggregator actor (feature-flag based) and adjusts related unit tests/utilities.
