[Enhancement]: Link all environment checks to PNIDs, regardless of system type

What enhancement would you like to see?

Currently environment checks are done in 2 different ways depending on the system type:

• 3DS - Checks the NEX account environment
• Wii U - Checks the PNID environment

Since beta whitelisting is only automatically set at the PNID level, and it's not possible to reliably automate whitelisting/unwhitelisting 3DS consoles, we should instead require beta testers to link a beta-allowed PNID to their 3DS. Our servers should then:

• Check for that linked PNID on the console
• If a PNID is linked, use that for environment checks
• If not, use the system/NEX account environment

This way we no longer need to worry about manually whitelisting 3DS users. We would also need to run a migration on the database to reset all (not banned) 3DS environments back to production, in order to catch any legacy users, enforce the PNID checks for new users, and catch any people left behind who had their 3DS account whitelisted but we never unwhitelisted it after they left beta

Any other details to share? (OPTIONAL)
