Notification policy (#4768)

This was so much work wow. I think it works pretty well and is the best
compromise between all the alternative we considered. Yes the
pull-to-refreh on the notifications works slightly different now when
the new bar is visible, but I don't think there is a way around that.

Things I plan to do later, i.e. not as part of this PR or release:
- Cache the notification policy summary for better offline behavior and
less view shifting when it loads
- try to reduce some of the code duplications that are now in there
- if there is user demand, add a "legacy mode" setting where this
feature is disabled even if the server would support it

closes #4331
closes #4550 as won't do
closes #4712 as won't do
