fix(sync): "Connecting…" only while catching up, not for 30 s after load (#274)

The strip showed for PREPARED and for the first SYNCING after it (or after
RECONNECTING), i.e. until the next /sync returned: ~30 s of long-poll on a
quiet account while the app already worked. A SYNCING means a sync just
succeeded, so the strip now shows only during CATCHUP; failures still show
as Reconnecting / Connection lost.

Fixes #274
