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.

- Replace characterToGlyphMapping with characterRects ([CGRect]?) on InteractiveTextNodeLine
- Add computeCharacterRects flag to InteractiveTextNodeLayoutArguments
- Compute actual glyph bounding boxes via CTFontGetBoundingRectsForGlyphs during layout
- Implement computeRevealedLines, layoutForCharacterCount, sizeForCharacterCount
- Implement updateRevealCharacterCount to distribute character budget across content item layers
- Update snippet layers to animate per-character rects with SnippetLayer tracking character index
- Mask limit driven by lowest animating snippet index for correct reveal ordering
- Fix listViewAnimationCurveEaseIn to match iOS default ease-in curve (0.42, 0.0, 1.0, 1.0)

Fix compilation errors in SubcodecAnimationCacheImpl and
SubcodecMultiAnimationRendererImpl: NSData->Data sink closure types,
withSink->sink argument labels for advanceFrame/emitFrameIfNeeded,
unused variable warning, and redundant Void return assignment.
Add both modules as deps to ChatEntityKeyboardInputNode to verify
they compile in the full build.

Implements utility helpers, BT.709 ARGB→YUV 4:2:0 conversion with alpha
un-premultiplication, and AnimationCacheItemWriterImpl that feeds frames
to SCSprite and writes metadata alongside the .mbs output.
