fix: give each Feeds top nav filter its own Account + LocalPreferences flow

- Follow Packs was piggybacking on the Discovery top nav filter; give it a
  dedicated defaultFollowPacksFollowList StateFlow, liveFollowPacksFollowLists,
  and a DEFAULT_FOLLOW_PACKS_FOLLOW_LIST preference key so its top nav filter
  no longer mutates Discovery (and vice versa).
- Persist Communities, Badges, Browse Emoji Sets, and Follow Packs top nav
  filters in encrypted SharedPreferences so they survive app restart.
- Longs top nav was restricted to kind3GlobalPeople; switch it to
  kind3GlobalPeopleRoutes to match the other media/reading feeds and expose
  hashtag/geohash/relay/interest-set filters.
