Restore write-back for dynamic callbacks.

ReflectorContext.CallMethod passes a copied IValue[] to dynamic targets and no longer copies changes back to arguments. A DelegateAction callback can assign an output value in that array, but the caller's ArrayImpl then keeps the old value.

Restore copy-back for dynamic calls, including when the target throws.

Update ReflectorContext.CallMethod to copy modified arguments from argsToPass
back into the original arguments for dynamic targets, in a finally path so
write-back also occurs when the callback throws. Preserve the existing behavior
for non-dynamic targets.

Restore skipped arguments only in the compiled-block adapter.

Do not reverse PopArguments globally. Fixed-signature calls use null for omitted parameters. NativeApiComponent.SetDefValues substitutes defaults only when arguments[i] == null.

Dynamic calls pass the array unchanged to DelegateAction. Its BslValue[] adapter is used by CompiledBlock and currently forwards null to the generated typed conversion. A typed string conversion then dereferences null.

Suggested fix 
         public DelegateAction(Func<IBslProcess, BslValue[], BslValue> action)
         {
             _action = (process, parameters) => action(process, parameters
-                .Select(x => x is IValueReference r ? r.BslValue : (BslValue)x)
+                .Select(x => x is IValueReference r
+                    ? r.BslValue
+                    : x ?? BslSkippedParameterValue.Instance)
                 .ToArray()
             );
         }

- 908:
Update the BslValue[] adapter in DelegateAction to convert null skipped
arguments to BslSkippedParameterValue.Instance before invoking the action, while
preserving IValueReference unwrapping. Leave PopArguments unchanged so
fixed-signature calls continue receiving null for omitted parameters.
