* Add recovery code support for two-factor auth When users enable two-factor auth, the app now generates ten single-use recovery codes. Users are encouraged to print the codes and store them in a safe place. The two-factor prompt during login now accepts both OTP codes and recovery codes. The two-factor settings UI allows users to regenerated lost recovery codes. Users who have set up two-factor auth prior to this feature being added can use it to generate recovery codes for the first time. Fixes #563 and fixes #987 * Set OTP_SECRET in test enviroment * add missing .html to view file names
