Wave 11: ActionSheetPeerItem de-Postboxed. Revisits wave-1 abandonment.
`postbox: Postbox, network: Network` init params collapse to
`stateManager: AccountStateManager`; avatar setPeer call routes via
`item.stateManager.postbox` / `.network`. Module never names Postbox.
Sole caller (ShareController.swift:1146) migrated in place.
Wave 12: HorizontalPeerItem de-Postboxed (same pattern). Ripples the
collapse up into ChatListSearchRecentPeersNode's public init
(`postbox:/network:` -> `stateManager:`). That module still imports
Postbox for PostboxViewKey/UnreadMessageCountsView internals but its
public surface simplifies. 3 external caller sites migrated.
Wave 13: AttachmentTextInputPanelNode minor cleanup. Module was already
Postbox-free at source level (wave 6) but carried a dead BUILD dep and
had 2 raw `peerId?.namespace == Namespaces.Peer.SecretChat` checks.
Both now use existing `PeerId.isSecretChat` extension in TelegramCore.
Wave 14: BUILD-dep sweep mirroring wave 6's source sweep. 98 modules
had `//submodules/Postbox:Postbox` (or `//submodules/Postbox`) BUILD
deps despite no source file importing Postbox since wave 6. Single
iteration, zero restores -- Bazel Swift requires source-level `import`
for symbol resolution, so redundant BUILD deps are pure metadata.
Net: 110 files, +116/-149. Build verified green (debug_sim_arm64).
