[Feature Request] Support email address changes for existing Claude accounts

Bug Description
If for some reason you cannot change the email accounts associated with your Claude account, Kama just tells you to create a new account, which I feel like is inefficient. I want to build a long-term relationship with one Claude account and be able to adapt my email addresses over time.
