Chore: add reserved username/password list

[Adammatthiesen]

currently commonly used unsafe names and passwords are not being checked, this issue would add a check and a list for that check of the most common names/passwords that should be blocked from registration. There are many lists online that are very similar, i would recommend we find a free-to-use list to base our list on.

Resources:

• Username-Blocklist
• Unsafe Common Passwords list
