Implement warning system enhancements with unique identifiers

- Added a `warningNumber` field to the `Warning` model for sequential identification of warnings.
- Updated the `createWarning` function to handle the new `warningNumber` logic and notify users via DM upon receiving a warning.
- Refactored moderation commands to utilize the new warning system, including changes to the warning creation and removal processes.
- Enhanced the WebUI to display warning numbers in the warnings table and updated localization for related messages.
- Documented changes in phase tracking to reflect the new warning system features.
