Implement command cooldown management and enhance command execution flow

- Introduced `applyCommandCooldown` function to manage per-command cooldowns after execution, improving command rate limiting.
- Updated command execution flow to include cooldown application, ensuring users are informed of cooldown status.
- Enhanced error handling in interaction replies, allowing for more graceful error management and user feedback.
- Improved the handling of interaction responses across various commands, ensuring consistent user experience.
- Added permission checks for new commands, ensuring only authorized users can execute specific actions.
