Traffic reduction and tuned caching strats (#2215)

* Update the feed to only check latest on focus after 30s, but to do a full reset on focus after 1 hour to avoid very stale data

* Remove the isFeedPublic query

* Fix: avoid double next-page fetches

* Reduce some poll intervals to reduce server load

* Guard against double-fires of fetchNextPage

* Reduce polling on blurred screens
