Add iOS peek long-press context menu for image embeds

Introduces expo-bluesky-context-menu, a compositional Root/Trigger/Menu/MenuItem wrapper around UIContextMenuInteraction. The preview ViewController is sized to the image's true aspect ratio so tall/panorama previews don't stretch mid-lift, and menu icons are rasterized from the app's SVG icon set on the native side. The preview prop is a discriminated union (image today; video and externalCard reserved) so the same module can back those embeds in follow-ups. https://claude.ai/code/session_015REmux3R9uuEMMJUHxTyQT
