Support basler backend in trigger defaults

Previously the default trigger configuration was only applied for backend 'gentl' and always stored under the 'gentl' properties key. This change treats the backend name dynamically (accepting both 'gentl' and 'basler'), and stores the default trigger settings under the actual backend key in cam.properties. Also preserves behavior when cam.properties or the backend namespace is not a dict.
