A button in the profile security tab to redo login

[h7io]

Describe the enhancement

In the Profile -> Security tab, where all the token stuff is, I would like a button/link which would redirect to the login/credential-entry page again and allow inputting new credentials. If the page is browsed away/canceled - nothing happens, the old login/credentials continue being used.

Use cases

I have implemented a credential rotation script, so that new credentials (with associated users) are added yearly and after a month - the old ones deleted.
To enter the new credentials - I have to log out in the mobile app, which breaks all my mobile widgets (they need reconfiguring after a new login) and if there is an issue with the new credentials - the old ones have already been cleared from the app, so I need to find the old ones to make the app work again.

The idea is that a way to login with a new user, while already logged in with an old, would prevent the mobile widgets breaking and would be a better overall UX for switching users in mobile.

Anything else?

I would appreciate even some guidelines what would need changing in the code, so I could prepare a PR, or just have a patch for my local instance if no one else is interested. I understand that the button needs to be added to HA frontend, but I am not sure which endpoint to call or how would the flow be best structured. So I would appreciate pointers.
