Form-field checked state

Returns TRUE / FALSE for checkbox / radiobutton fields, NA for other field types. The check honours the current selection state PDFium tracks; it falls back to inferring TRUE when the field value is non-empty and not the "Off" sentinel (matching the tibble view's inferred-checked logic). Wraps FPDFAnnot_IsChecked.
