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.

The left thumb was wrongly associated with the fpc 14 (left four fingers
taken simultaneously).

This is a temporary patch, to allows the import of the modules for
documentation purpose.

The buttons should now be the correct size in regards of the outer div,
even when the page is resized.

Before, for some page size, when there was just not enough space for one
button more, the outer div was shrunk, but the button was not, hence
producing an overflow of the button, which was not nice to see.
