fix: three critical bugs in scheduled send and account switcher

Bug 1 — Video recorder freeze with SendDelayManager enabled
When SendDelayManager is active, video notes (кружки) and media are
enqueued into Namespaces.Message.ScheduledLocal, not the main chat
history. This broke setupSendActionOnViewUpdate which expects the message
to appear in the regular history before triggering its callback (dismiss
recorder, collapse input). The callback never fired → recorder overlay
stayed on screen → app froze.

Fix: in requestVideoRecorder's completion closure, detect when
SendDelayManager.shared.isEnabled, immediately dismiss the recorder and
clear the interface state, bypassing the broken animation path.

Bug 2 — Scheduled messages remain visible after being sent
When AntiDeleteManager is enabled, the .DeleteMessages case in
AccountStateManagementUtils uses  to skip non-Cloud namespaces
(ScheduledCloud, ScheduledLocal). However after the loop no code
physically removed those skipped messages from Postbox — they stayed
in the scheduled list forever, appearing as 'planned' messages that
never disappeared.

Fix: collect non-Cloud IDs during the Anti-Delete loop and physically
delete them via _internal_deleteMessages after the loop.

Bug 3 — Account switcher avatar not loading
Race condition in avatar loading: resourceData was subscribed to first,
then fetchedMediaResource triggered the network fetch. The signal's
 callback fired before data arrived, calling buildButton(nil)
which discarded the real avatar.

Fix: trigger fetchedMediaResource first, then subscribe to resourceData
with filter { $0.complete } |> take(1) so the signal stays alive until
the download completes.
