[Feature] Feature to easily switch between User-Accounts on Mobile

Currently, if you want to switch to another account (even on the same immich instance) you have to log out of the current one. And type in credentials all over again.

Suggestion: Click on the User icon and have the option to switch directly to a logged in account (similair to how streaming services handle it e.g. Moonfin).

Why? If somebody uses more than two accounts it is really annoying to have to inout credentials everytime.
