[Feature] Monitor DLNA Watch Activity

[AdultSun]

Is your feature request related to a problem? Please describe.
Currently, watch activity is only monitored within a web browser. Any plays over DLNA is not tracked at all.

Describe the solution you'd like
Plays over DLNA should be monitored the same way as plays in the web browser. Stash should update the last played date, play counter, play duration, and progress tracker accordingly.

Even better would be to allow DLNA and web browser tracking to be turned on/off separately. I only ever use the web browser to preview videos and do not want any of that activity to be tracked. I always use DLNA to watch scenes instead. I would want Stash to only monitor watch activity over DLNA and to ignore all watch activity from the browser. However, the current system is the exact opposite of that scenario.

Describe alternatives you've considered
A nice stopgap for me would to allow for manually adjusting watch history as needed instead of leaving everything to automatic tracking. I could leave monitoring switched off and just manually input anything I want saved. This would be helpful for other scenarios as well and I've submitted it as a separate feature request (#3680).
