Forms - Advanced Validation

Currently Siteglide handles both server-side and client-side validation, but only for required: true/false.

We could add further validation options, possibly following the same options pOS provides for forms:

One of the useful parts of that is that some fields can be conditionally validated, so if field a is filled in, field b becomes required etc.

It would be useful if validation could also have an “exceptions” box where validation is disabled per form layout, in case there is an “admin” form layout where less rules apply. Though this may be tricky to design security for.

This helps handle cases where the validation is too strict for the flexibility with which forms need to be used sometimes, including across different layouts.
