Refactor reaction handling and tag response types for improved type safety

- Updated the event handler for message reaction removal to enhance type safety by specifying user types.
- Changed the return type of the buildTagReply function from MessageReplyOptions to InteractionReplyOptions for better compatibility with interaction responses.
- Adjusted embed handling in tag creation and update functions to use undefined instead of null for consistency.
