ticket to close

Approach

Add custom validation tags for forms that will grab what is needed at form generation.

Assorted Notes/Considerations/Learning

Initial plan was to use string parsing similar to how we handle regex in the webform api, but this exposes us to injection for function handling. Tag system could become cumbersome if we have too many custom validations, but this is not foreseen to be the current plan for webforms.

I truly love that you got this to work and we can define rules via type in a switch statement. I think its a great solution, and im stoked we have the ability to do custom validations now it really makes me feel more confident in our ability to say yes to those one off requests. thanks for tracking this down D 🥇

I think i added most of this code to the main branch cause i wanted to see it work. But i still cant get it to validate, im sure im doing something wrong. All that to say, if you wanted to use 'main' and figure out where the bug is and close this pr it might be easier than trying to figure out the deploy issue here
