fix: email encoding should replace ALL allowed characters

[ferreiro]

Bug description

This is a historical bug that mailcheck library (the one we're replacing) has had since the beginning.

mailcheck encoded the email to prevent XSS, but kept some characters unencoded to be compliant with RFC 5322. However, their function to replace characters only replaced the first character, since they forgot to run the spaces globally.

I noticed this while performing some tests of this library in our main application for ZooTools, an email with spaces like [email protected] was returned encoded

Description of change

I updated the regex to be run glob ally across every character. This will take a bit longer to validate the email, but it's blazing fast anyways and it's only run once when the email is being passed.
