Resolving multiple conflicts is an awful experience

### Is your feature request related to a problem? Please describe.
I migrated to a new phone and setup the nextcloud app and got conflicts for all of my images. There is no way to easily solve this without manually clicking each conflict and selecting the proper file (and I have over 100 of these so it's a god awful process). What's worse is after you solve a conflict it stays in the UI so you have to constantly remember which ones you already did as it takes a while for them to resolve and disappear. The whole experience is very bad if you have a lot of these.

### Describe the solution you'd like
Give me a better UI from the conflict list that allows me to select the server or local version without having to jump into another dialog to do so. Also give me an option to easily select all or many of them and resolve them all in one go.

Also show a loading bar or something on the ones that are re-processing so you know which ones you have already fixed.

### Describe alternatives you've considered
Blocking the conflict notification from appearing at all. Not a fix at all but gives me my sanity back.
