fix(calendars): wire feeds into updateFeedsWith so new events stream in live + drop redundant Calendar Lists label

Two things turned out to be the same bug:

1. New calendar events arriving from relays didn't show up in either
   feed without a manual pull-to-refresh. The screen was stuck on
   whatever the last full refresh saw.
2. After a top-nav filter switch the feed looked like it was reflecting
   "a previous state" — same root cause: filter switch ran a full
   refresh from LocalCache, but events that the new subscription
   subsequently delivered were dropped on the floor.

AccountFeedContentStates.updateFeedsWith / deleteNotes had calls for
every other feed but neither calendarAppointmentsFeed nor
calendarCollectionsFeed — so LocalCache.live.newEventBundles flowed
past them. Added both calls (and the matching deleteFromFeed entries)
so new appointments/collections insert into the visible feed live.

Also dropped the redundant "Calendar Lists" label above the top-nav
filter spinner on the collections screen — it duplicated the screen
title shown by the navigation chrome.
