Drop the SCROLL live-refresh FT — untestable under in-memory channels, IT-covered

RoomScrollLiveRefreshTest could never pass: ChannelsLiveServerTestCase runs
daphne in a SEPARATE PROCESS, and the test settings force the in-memory channel
layer, so a group_send issued from the test process (via record() → on_commit)
can't reach the consumer in the daphne process — the scroll_update nudge is
undeliverable no matter how correct the feature is. (Probed it: WS open, the
scroll-status endpoint returns the new row, but the browser logs 0 nudges.)
Production uses Redis, which is cross-process, so the live refresh works there.

Every link is already covered by ITs, so the E2E hop is the only gap:
record() schedules the broadcast on_commit (test_record_broadcasts_scroll_update_
on_commit), RoomConsumer relays it (test_receives_scroll_update_broadcast), and
the re-fetched feed partial renders the latest events (ScrollStatusViewTest).
Replaced the FT with a NOTE documenting why there's no FT + where the coverage
lives. Unblocks the channels CI stage.
