refactor(dcl): simplify ValueFormatter now that SDK returns native .NET arrays

The LmxProxy client's ExtractArrayValue now returns proper .NET arrays
(bool[], int[], DateTime[], etc.) instead of ArrayValue objects. Removed
the reflection-based FormatArrayContainer logic — IEnumerable handling
is sufficient for all array types.
