Need ability to add dynamically callable script hooks for Data Documents e.g. to show/hide field conditionally

[itadapter]

We will base this on metadata and scripting expressions

• https://github.com/azist/azos/tree/master/src/Azos/Scripting/Expressions
• Need transpilation into JS/other languages in addition to execution

Draft:

Appointenmt_2025

[Field]
public bool Good{ get;set;}

[Field(metadatacontent: "./")]
public string ReadNewspapers{ get; set; }

========================

Appointment_2025.laconf

meta
{
  ReadNewspapers
  {
    description="''''''''''''''''''''''''''''''''''";
    metadatacontent
    {
      scripting
      {
        isVisible{ this.jjjjj=="SpecialValue" }
        isRequired{  ..... }
      }
    }
  }

}

BUG: When we marshal schema the top level "meta{type-path...{" is lost at transmission, therefore Tristan does not get it and Unity code can not load expression tree properly because type-path is excised

[itadapter]

This is NOT a bug, but caching issues- we were looking at an older cached schema cached on disk
