fix: image upload on RN 0.83+ New Architecture

[Enixma]

What

Makes FormData image upload work on React Native 0.83+ New Architecture (Android + iOS). Two independent fixes are needed:

1. SDK / axios (Bug 2) — axios can't recognize React Native's FormData (no Symbol.toStringTag) and re-serializes the body as application/x-www-form-urlencoded instead of multipart/form-data; the upload server rejects it (multipart != application/x-www-form-urlencoded). Consumed here via patch-package on @amityco/ts-sdk-react-native@7.22.1-f15e84ea.0 until the fix ships in an SDK release. See AmityCo/AmityTypescriptSDK#1446.
2. React Native native (Bug 1) — RN 0.83.0's getBodyPreview() drained the one-shot multipart stream before send ("Stream Closed"). Fixed upstream in 0.83.1 (Fix binary FormData uploads on Android react/react-native#54917). Bump react-native (and @react-native/*) 0.83.0 → 0.83.1.

Files

• patches/@amityco+ts-sdk-react-native+7.22.1-f15e84ea.0.patch — the SDK fix (applied via the existing postinstall: patch-package).
• package.json / package-lock.json — RN 0.83.0 → 0.83.1.

Verification

FileRepository.uploadImage returns a real fileId; on-wire Content-Type is multipart/form-data (was urlencoded):

Platform	RN
Android	0.82.0, 0.83.1, 0.85.3, 0.86.0
iOS (simulator)	0.83.1
