Since the variable is global anyway, we don't need to pass it as
parameter.

The fetch of the data don't need to be done in an ajax query once the
page is loaded. This will directly populate the "secret" javascript
variable and the 'input' field.

The remaining time and the current TOTP are not useful in the current
workflow.

This is the same order as for the other pages (help on the left, next on
the right).

This will only use one div to the errors and OK messages. The
notification for the use is done via a function call instead of editing
the corresponding divs.

This will not display a message to the user if the TOTP is correctly
set, but will redirect him to the next step automatically.

The user is now obligated to provide the TOTP value to continue. If not
provided, the user can still re-open the current page to get help or
retry the configuration process. This should remove the miss configured
account by not reading the configuration dialog (the user has to provide
at least once the TOTP to be able to finish the configuration; if the
TOTP value is set in the database, the configuration has been done at
least once).

Remove the db.get_account_type_id_name() function and remplace it with a pre-fetched version at startup

This will lower the potential cost of this function against the database
by computing it only once at startup.

This helps readability in the code.

taken simultaneously).
