Maycon Santos 1d9fced073 [management] Add redis cache (#3516)
Refactor IdP user data caching by introducing a Redis cache implementation alongside an in-memory fallback, adding a Marshaler interface for flexible serialization, and updating related tests and account management code.

- Added a new cache store implementation with support for Redis and in-memory backends.
- Introduced Marshaler and wrapper types for handling serialization with msgpack and JSON.
- Updated account and user management modules to integrate and test the new caching strategy.
