Refactor ephemeral message handling in ticket interactions

- Updated ticket command and interaction responses to utilize the new `ephemeral()` function for consistent ephemeral message handling.
- Enhanced error handling for member fetching in ticket interactions, ensuring proper responses when members are not found.
- Improved localization for new error messages related to member presence in ticket commands.
- Documented changes in phase tracking to reflect updates in ticket interaction responses.
