Fix add authentication page

There is a regression in go-gitea#16199 whereby the add authentication page
fails to react to the change in selected type.

This is due to the String() method on the LoginSourceType which is ameliorated
with an Int() function being added.

Following on from this there are a few other related bugs.

Fix go-gitea#16541
