Brings app auth controller handling aligned within the app, rather than
having many overrides of the framwork packages causing confusion and
messiness over time.
- Restructured some of the route naming to be a little more consistent.
- Moved the routes about to be more logically in one place.
- Created a new middleware to handle the auth of people that should be
allowed access to mfa setup routes, since these could be used by
existing logged in users or by people needing to setup MFA on access.
- Added testing to cover MFA setup required flow.
- Added TTL and method tracking to session last-login tracking system.
Also added testing to cover as part of this in addition to adding the
core backup code handling required.
Also added the standardised translations for switching mfa mode and
adding testing for this switching.
Also continued a bit on the MFA verification system.
Moved some MFA routes to public space using updated login service to get
the current user that is either logged in or last attempted login (With
correct creds).
