We can create a new separate page consisting of multiple tabs that can show various graphs and tabular reports.

There are a few things we changed in this issue:

1. We added new phx authentication so that it can be easily applied to live view authentication.
2. To allow users to use the same credentials we have to manage the same password encryption. The only difference between phx auth and pow is the salt and base64 algorithm they use to encrypt the password. So we forked the pow library and started using the new base64 extension instead of the old Base module.
3. We wrote a new password migration script so that we can change all the old password hashes to the new Base64 password hashes.
4. Now the user has to login again (one time if he wants to access the live view dashboard.)
