Profile page gets "Sign into another account" beside Log out.

The additive sign-in door lived only at the foot of the Accounts screen; the
profile page — where people actually go looking for a way out of the current
identity — offered just Log out. Now it carries the same button, via a shared
signInAnother action on the feature ctx (clears the profile/chat state so the
unlock screen's Back lands on the wallet, and the new identity doesn't open
onto the old identity's profile).
