Move global "Sign out" out of the current account row (#4941)

* Rename logout to logoutEveryAccount

* Add logoutCurrentAccount()

* Make all "Log out" buttons refer to current account

Each of these usages is completely contextual and refers to a specific account.

* Add Sign out of all accounts to Settings

* Move single account Sign Out below as well

* Prompt on account removal

* Add Other Accounts header to reduce ambiguity

* Spacing fix
