Register Feature and improvements

Hello,

at the moment it is possible if ALLOW_REGISTER=true that you can only register with a username and password. In my opinion it would be better if you can register with an e-mail and password, but you have to verify the e-mail address to log in to the account. It might also be good to add a captcha to prevent bots from registering.

In my opinion you would have to offer an integration with google recaptcha or similar providers.

We need variables for the .env so that we can then define an email server which is used to send the confirmation emails.

The admin should also have an overview of which accounts are registered so that data can be easily deleted / users can be easily deleted. (GPDR) This is currently not possible as far as I can see.

Also a small feature that should be offered is that when you click on your profile you also get to the profile settings, at the moment this does nothing and you have to go to the ‘Profile’ menu via the three dots.

And thank you for this software. It helps a lot :)

Break the request into separate registration, email verification, CAPTCHA, email configuration, account administration, and profile-navigation tasks. Start by tracing the ALLOW_REGISTER flow and the existing profile and admin entry points; the issue provides no files or tests, and completion would require agreed scope and acceptance criteria for each feature.
