fix(permission_system): streamline cache handling for command permissions

- Simplified the cache retrieval logic by directly unwrapping values and removing unnecessary checks for malformed entries.
- Improved logging to provide clearer messages for cache hits, enhancing traceability during cache operations.
- Ensured that uncached commands are accurately tracked, improving overall cache management efficiency.
