fix(symbol-config): coerce int access to genuine enum via type(maximal_access)

Browse source 
When _resolve_access falls back to a plain int (because the
'from scriptengine import SymbolAccess' import returned a hollow
object on this SP), the C# setter rejects every non-zero int:

    Cannot convert numeric value N to SymbolAccess.
    The value must be zero.

Only 0 (=None) survives the implicit conversion. Recover by parsing
the int through the enum class type we just got from
var.maximal_access (which is always a genuine SymbolAccess value
because it came back through the same scriptengine that's about to
accept it). DEBUG print for both the success and failure paths.
