Email validation API endpoints aren't implemented

[InternalLoss]

The relevant inputs to both resend the confirmation code email (which should change the confirmation code), and entering the confirmation code, do not work. I've purposefully kept my PNID unverified to ensure this is fixed.

Further context:

Console will PUT https://account.nintendo.net/v1/api/support/email_confirmation/$NNID_PID/$6DIGITVERIFCODE

If invalid: HTTP 400, and error:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><errors><error><code>0116</code><message>Missing or invalid verification code</message></error></errors>

If valid: HTTP 200 OK

Validated date should be set to current date and time as the console will request this from profile:

        <validated>Y</validated>
        <validated_date>2021-03-05T13:43:12</validated_date>
