What does this PR do?(Please give us a brief description of what this PR does.)
This fixes an issue caused by changing alwaysMarkNsfw to be what the boolean calls it way back about a year ago forcing users files to be stuck as sensitive when toggled by admins/mods.
This unfortunately had the side-effect of breaking the Mark as Sensitive by default option in settings/drive which also relied on the same boolean to fix this I simply add a new boolean specifically for that toggle.
(This issue does not affect remote users only local)
