feat(filters): improve RegexField validation (#803)

* make sure fields are validated on page load

* make red border only show if useRegex enabled

* ensure tooltips have higher z-index in RegexField

removed z-index in customtooltip.tsx as its causing issues with tooltips in other components

* improved regex validation

return false for cases that are unsupported by Go

* improved check for unsupported conditionals
