fix(mobile): stop shared content errors in Personal Team builds

[t3dotgg]

Personal Team iOS builds intentionally omit App Groups, but the active Expo manifest could still report incoming sharing as enabled. That made every foreground refresh call expo-sharing without an App Group ID and show a repeated import error.

Treat Expo's missing-App-Group error as an unavailable incoming-share inbox and cache that binary capability. Other native sharing failures continue to surface.

Tests: focused sharing tests, mobile typecheck, targeted lint, and formatting.

Overview
Personal Team iOS builds omit App Groups, but incoming sharing could still be treated as enabled, so foreground refreshes repeatedly called expo-sharing and surfaced import errors.

A new createIncomingSharePayloadReader wrapper treats expo-sharing’s ERR_FAILED_TO_RESOLVE_APP_GROUP_ID on iOS as an unavailable inbox (empty payloads) and caches that state so later reads don’t hit native code again. IncomingShareProvider wires this reader into IncomingShareInbox instead of calling getSharedPayloads directly. Other native failures still throw.

Note

Fix shared content errors in Personal Team builds by handling missing iOS App Group

• Adds createIncomingSharePayloadReader in incoming-share-native.ts to wrap native payload reads with error handling specific to iOS Personal Team builds.
• When the iOS App Group is unavailable (ERR_FAILED_TO_RESOLVE_APP_GROUP_ID), the reader treats it as an empty inbox and memoizes the unavailable state to skip future native reads.
• All other errors continue to propagate normally; non-iOS platforms pass through unchanged.
• Behavioral Change: IncomingShareInbox.getPayloads now returns [] instead of throwing when the iOS App Group is missing.

Approvability

Verdict: Approved a11d375

Straightforward bug fix that adds graceful error handling for iOS Personal Team builds where App Group is unavailable. Instead of crashing, the sharing inbox returns empty. Change is self-contained with comprehensive tests and limited to a specific iOS error case.
