DaVinci resolve 19.1.2 update: fixes and enhancements

The DaVinci Resolve 19.1.2 update introduces enhancements such as improved audio fade playback on clips with effects, better handling of Open EXR metadata, and more reliable dongle recognition for DaVinci Resolve Studio on Windows. While the free version offers the same processing quality as the Studio variant, it limits output to Ultra HD and supports a single GPU. The update also resolves potential DRFX naming conflicts and includes general performance and stability improvements.
