🎨 feat(api-server): Add TTL caching to authentication repositories 🚨

[pcrespov]

What do these changes do?

This PR implements TTL-based caching for authentication operations to improve performance and reduce database load.

🚀 New Features

• Added aiocache with 120s TTL to ApiKeysRepository.get_user() method
• Added aiocache with 120s TTL to UsersRepository.get_active_user_email() method

🔧 Configuration

• Cache can be disabled via AIOCACHE_DISABLE=1 environment variable
• Uses in-memory backend by default with automatic TTL cleanup
• Added proper cache namespacing and noself=True configuration

Security Considerations

• API secrets are never stored in cache secrets (only public API keys used for cache identification)
• Short 120s TTL ensures revoked access doesn't persist long
• Cache keys use only non-sensitive identifiers

Performance Impact

• Reduces database calls for repeated authentication requests
• Estimated memory usage: ~200-500 bytes per cached entry
• Suitable for applications with <10K active users

Related issue/s

• resolves [Maintenance]: Improve Get keys database endpoint #8461

How to test

• Added comprehensive cache effectiveness test in test_repository_api_keys.py
• Test validates both performance improvements and database call reduction
• Added test documentation covering memory implications and configuration optio

cd services/api-server
make install-dev
pytest -vv tests/unit/_with_db/authentication 

Dev-ops

• 🚨 When deployed measure the effect on the db calls (e.g. AIOCACHE_DISABLE=1) and compared to results in [Maintenance]: Improve Get keys database endpoint #8461
