fix: resolve cache value display issue across all drivers (Redis, File, Database) (#3)

* fix: resolve cache value display issue across all drivers (Redis, File, Database)
Fix cache:list command showing (null) values by implementing driver-specific fallback logic. Added proper prefix handling for Redis, file content parsing for File driver, and universal error handling for all cache drivers.

* add fix

* Remove value preview functionality and enhance test coverage
- Remove getValuePreview() method and related value display functionality
- Remove ValuePreviewTest.php and related test cases
- Simplify command output to show only cache keys without values
- Add comprehensive unit tests for CacheUiLaravelCommand private methods
- Add tests for CacheUiLaravelServiceProvider and CacheUiLaravel Facade
- Improve test coverage across all package components
- Update command interface to focus on key listing and deletion only
