Isaac b2ba4b5878 Postbox -> TelegramEngine wave 7: last TelegramEngine.* facade leaks ...

Closes the seven remaining raw-Postbox leaks in TelegramEngine public
facades surfaced by a post-wave-6 scouting pass (all non-permanently-
blocked candidates).

Facades migrated in place (6 rewrites + 1 deletion; all _internal_*
implementations unchanged per the "internal Postbox-facing stays raw"
rule):

  Messages:
    downloadMessage                          Signal<Message?>           -> Signal<EngineMessage?>
    topPeerActiveLiveLocationMessages        Signal<(Peer?, [Message])> -> Signal<(EnginePeer?, [EngineMessage])>
    getSynchronizeAutosaveItemOperations     deleted (dead facade; sole caller uses _internal_ directly)

  Peers:
    updatedRemotePeer                        Signal<Peer>  -> Signal<EnginePeer>
                                             (PeerReference param kept; no EnginePeer.Reference alias today)

  Resources:
    renderStorageUsageStatsMessages          [EngineMessage.Id: Message]  -> [EngineMessage.Id: EngineMessage]
    clearStorage(peerId: ...)                [Message]                     -> [EngineMessage]
    clearStorage(peerIds: ...)               [Message]                     -> [EngineMessage]
    clearStorage(messages:)                  [Message]                     -> [EngineMessage]
                                             (no external callers; migrated for overload-set consistency)

Consumer call-site updates (5 files):
  - ChatListSearchListPaneNode       drop redundant .flatMap(EngineMessage.init) wrap
  - LocationViewControllerNode       drop redundant .map(EngineMessage.init) wrap
  - LiveLocationSummaryManager       drop redundant EnginePeer(...) / EngineMessage(...) ctors
  - StorageUsageScreen               bridge [Message] <-> [EngineMessage] at the 4 facade-call points
                                     (internal [MessageId: Message] / [Message] storage kept;
                                      full-consumer-module migration is out of scope)

Discovery: grep of TelegramEngine/*/TelegramEngine*.swift public signatures
for `: Postbox|: Account|: MediaBox|: MediaResource|: Peer\b|: Message\b|
-> Signal<.*(Peer|Message)` turned up these seven candidates and no others.
After this wave, the full TelegramEngine.* facade surface is engine-typed
modulo the four permanently-blocked TelegramMediaResource-conforming
classes recorded in CLAUDE.md (ICloudFileResource, InstantPageExternal-
MediaResource, VideoLibraryMediaResource, YoutubeEmbedStoryboardMedia-
Resource).

No modules became Postbox-free in this wave. Plan: docs/superpowers/
plans/2026-04-20-postbox-to-telegramengine-wave-7.md.

Full project build verified green.
