chore(tests, dependencies, build): optimize test assertions, fix mocking issues, and update dependencies

- Simplified test assertions by removing redundant type casting in `ResultTest`.
- Improved Redis mock behavior and verification leniency in `RedisDistributedCacheTest`.
- Updated dependency versions in `libs.versions.toml` (e.g., downgraded `ktor` and adjusted `composeMultiplatform`).
- Refined Gradle build scripts for consistent compiler args and testing configurations (e.g., disabled browser tests in frontend).
- Addressed mocking issues in `RedisDistributedCacheTest` to prevent `NoSuchMethodError`.
- Fixed package imports due to framework updates in Spring Boot and Micrometer-related components.
