Previously, we could edit the cloud credentials in basically two
places. At startup of the app from a fresh install (and no previous
data on the device), and from the settings. Issue #515 proposes
only one way.
However, we need a way to access the new credential UI pages, so
that the pages at a fresh install of the app can be reused,
for example for account switching.
This commit replaces the settings cloud credentials block by
a simple (not editable) display of the current credentials, and
a button to access the initial pages, for all management tasks
on the credentials.
