libSceNetCtlApDialog technical debt

libSceNetCtlApDialog - the access-point dialog shows no UI and reports user cancellation without bringing up a connection. Parameter size, reserved-byte checks, option-string limit and lifecycle errors are recovered from the supplied module. The meaning of the input word at offset 56 and service-side connection behavior remain unresolved.
sceNetCtlApDialogGetResult - returning COMMON_DIALOG_ERROR_ARG_NULL for an unwritable result pointer is a host-safety fallback with console behavior unmeasured.
