This commit removes unused language files and preserves the English sources for Crowdin. The account confirmation page has also been re-skinned with the current login/register template.
Some missing translations for 2fa were also added to the main messages file.
Sources for translations for the menus were also added.
This commit adds a password strength requirement for new users using
regular expressions.
Also adds a dismissable alert so users know how to create passwords
properly.
This commit fixes some superficial instances of Broken Access Control
(https://owasp.org/www-project-top-ten/OWASP_Top_Ten_2017/Top_10-2017_A5-Broken_Access_Control).
There may be some more instances of this, as authorization was only done
after most of the controllers were done (big mistake).
Some refactoring was also performed, where Route Model Binding with DI
(dependency injection) was used whenever possible, to increase
testability of the codebase.
Some reused code was also moved to Helper classes as to enforce DRY;
There may be some lines of code that are still copy-pasted from other
parts of the codebase for reuse.
Non-breaking refactoring changes were made, but the app as a whole still
needs full manual testing, and customised responses to HTTP 500
responses. Some errors are also not handled gracefully and this wasn't
checked in this commit.
