Isaac f84e94f507 MediaResource → EngineMediaResource refactor: wave 2
Drive raw `MediaResource` out of the `TelegramEngine` public facade for
photo-upload APIs, and complete a first batch of consumer-side
migrations. Behavior-preserving. The `_internal_*` Postbox-facing
functions are untouched — only the facade signatures change, bridging
inside via `_asResource()` / `EngineMediaResource(_:)`.

TelegramEngine facades migrated (signatures now take EngineMediaResource):
- TelegramEngine.Peers.uploadedPeerPhoto / uploadedPeerVideo
- TelegramEngine.Peers.updatePeerPhoto (closure param too)
- TelegramEngine.AccountData.updateAccountPhoto / updateFallbackPhoto
- TelegramEngine.Contacts.updateContactPhoto
- TelegramEngine.Auth.uploadedPeerVideo

Consumer-side changes:
- MapResourceToAvatarSizes utility: signature is now
  (engine: TelegramEngine, resource: EngineMediaResource, ...). Uses
  engine.resources.data(id:) internally. The submodule drops
  `import Postbox` and the Bazel dep.
- AuthorizationUI: avatar-video signal retyped from
  Signal<TelegramMediaResource?> to Signal<EngineMediaResource?>.
- 27 `mapResourceToAvatarSizes(postbox:...)` call sites across 5
  TelegramUI/TelegramCallsUI files migrated to the new form.

Deferred:
- SaveToCameraRoll (planned Task 8) abandoned — module has three
  public functions taking `postbox: Postbox` (umbrella-type leak,
  banned by rule 2) and requires a full module-migration wave, not a
  type swap. Reason recorded in the wave-2 plan doc.
- Other TelegramEngine facades still leaking MediaResource
  (TelegramEngineStickers.uploadSticker; UploadSecureIdFile.* —
  additionally leaks Postbox) flagged for a future wave.

Docs:
- CLAUDE.md: new rule 7 (TelegramCore never imports UIKit/Display,
  shared with Telegram-Mac), and a new "MediaResource →
  EngineMediaResource consumer migration" section describing the
  wrap/unwrap helpers and the modify-in-place facade-bridging
  pattern.
