(Security) Integrate recheck for RegExps

• Confirm regexes are safe
• If not safe, prevent execution

Tried integrating recheck but found its execution to drastically slow page loading loading times, which would impact user experience.

Also explored only running recheck in local dev environments as a workaround that would still provide us the opportunity to catch vulnerabilities without affecting users.

Ultimately it seemed best to simply refactor and eliminate usage of dynamic regexes in favor of plain String functions.
