ui: add typed value conversion errors

Browse Source 
Replace boolean output-parameter converters with UIValueResult so conversion failures can provide numeric codes and optional diagnostics without exposing partially converted values.
Expose observable converter error state from UIDataBind, UIProperty, and UIValueBinding.
Reject invalid widget input without changing the model or propagating it to sibling widgets, while keeping programmatic model updates authoritative.
Migrate ecode's custom output parser converter, expand binding tests, and document the data-handling architecture and next form-validation
phase.
