refactor(infra-cache): Refine module with Kotlin idioms and robust tests

Browse Source 
This commit introduces a comprehensive refactoring of the cache module to improve code consistency, API ergonomics, and test robustness.

Code Refinements & Improvements
Standardized on kotlin.time: Replaced all usages of java.time.Instant and java.time.Duration with their kotlin.time counterparts (Instant, Duration). This aligns the module with the project-wide standard established in the core module and avoids type conversions.

Added Idiomatic Kotlin API: Introduced inline extension functions with reified type parameters for get() and multiGet(). This allows for a cleaner, more type-safe call syntax (e.g., cache.get<User>("key")) for Kotlin consumers.

Code Cleanup: Removed redundant @OptIn(ExperimentalTime::class) annotations from data classes by setting the compiler option at the module level in cache-api/build.gradle.kts.

Testing Enhancements
Stabilized Offline-Mode Tests: Re-implemented the previously disabled offline capability tests. The new approach uses MockK to simulate RedisConnectionFailureException instead of trying to stop/start the Testcontainer. This allows for reliable and robust testing of the "dirty key" synchronization logic.

Fixed Compilation Errors: Resolved various compilation errors in the test suite that arose from the type refactoring and incorrect mock setups.
