fix(android): resolve multiple Android-specific bugs

- Fix validateImage returning 'issues' instead of 'errors' to match iOS/TypeScript
- Fix fiveCrop 'array already consumed' by removing duplicate putArray calls
- Fix extractVideoFrames returning 0 frameCount by tracking count separately
- Add backwards-compatible error handling in App.tsx for validation results
- Add safety guard for regions array in cutout result handling
