This commit aims to improve the user experience when using payment acquirers. There currently are no error feedback with some acquirers, which leaves the user wondering what is going on and what is the real status of its payment.
In some cases, the user is currently being redirected to the home page even though the payment has failed. We want to make it more obvious to the user that something unexpected has happened by redirecting to an intermediate page that will provide good feedback on payments status.
Another goal of this commit is to order acquirers by sequence instead of by flow and to select the first acquirer by default. This feature was already implmented in commit fe294fd43e521bd2d339e962f43acf46c3d4cb97, some UI adaptations were needed though.

* make CSRF protection the default on all non-SAFE methods
note: there currently is no way to call a CSRF-protected endpoint
without a form-encoded entity-body as that's the only place we get the
CSRF token from.
* simple CSRF token generation: just use the HMAC'd session id, no
generating a new random token per session then HMAC it
* use constant-time equal function to avoid timing attacks
* assert that a database secret is configured before hashing/validating
the CSRF token
* opt-out database manager from CSRF: The super-admin password serves
the purpose of a CSRF token in the database manager screens.
There is no request database to obtain the
secret and generate a CSRF token.
