Isaac ad85ef6517 Postbox → TelegramEngine refactor: wave 1 ...

Drop direct `import Postbox` from four leaf consumer submodules, routing
data access through TelegramEngine/TelegramCore. Behavior-preserving.

Consumers migrated:
- ChatInterfaceState
- ChatSendMessageActionUI
- ContactListUI
- DrawingUI

TelegramCore additions (typealiases + one EngineData item):
- EngineMemoryBuffer, EnginePostboxDecoder, EnginePostboxEncoder,
  EngineAdaptedPostboxDecoder (narrow utility aliases for coding support)
- EngineData.Item.Configuration.ContactsSettings

Six planned modules were abandoned in wave 1 with reasons recorded in
the plan: ActionSheetPeerItem, ChatListSearchRecentPeersNode,
DirectMediaImageCache, FetchManagerImpl, GalleryData, ICloudResources.
Each either has a public API that leaks `Postbox`/`Account`/`MediaBox`
(banned umbrella-type aliases) or cascades into out-of-wave modules.

CLAUDE.md now records the wave rules, typealias cheat sheet, and the
wave-selection guidance learned from this pass.
