Show the account feed after it loads

Refresh fetched the account feed correctly -- the status line said "60 videos
in feed" -- and the page stayed empty with "No subscriptions yet" on it.

The empty-state hint added in 5.5.0 hides the grid so it can sit centred
rather than pinned under a large blank area. Every path that changes the grid
re-runs that check afterwards and shows it again; the account path was the one
that did not, so the grid stayed hidden from startup no matter what was loaded
into it. The local feed re-runs it and was unaffected, which is why this only
showed up for someone signed in.

Two related things while here. The empty-state message was written for local
subscriptions and is wrong advice in account mode, which does not use them --
it now says to press Refresh rather than to go and subscribe to something. And
the Subscriptions panel, which lists local subscriptions, is hidden in account
mode instead of sitting empty beside a full feed and implying something failed.

+- **The account feed loaded but never appeared.** Refresh reported "60 videos in
+  feed" above a "No subscriptions yet" message and an empty page: the empty-state
+  hint hides the grid so it can sit centred, and the account path set its entries
+  without re-running that check — so the grid stayed hidden from startup. The
+  local feed was unaffected, which is why it went unnoticed.
+- The empty-state message was written for local subscriptions and was wrong
+  advice in account mode, where local subscriptions are not used at all. It now
+  says to press Refresh instead of telling you to go and subscribe to something.
+- The Subscriptions panel is hidden in account mode rather than sitting empty
