Subject: [PATCH] fix: make Discover's pull-to-refresh re-issue the discovery
 REQs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pull-to-refresh only re-read the cache (invalidateData), so when cached
beats were stale it showed the loss instead of fixing it. The DVM tab's
refresh now also invalidates the discovery assembler, re-issuing the 31990
REQ and both heartbeat streams (global + outbox batches) with fresh rolling
windows — beats repopulate in seconds instead of whenever the open REQs
happen to deliver.
