- api() in apps/mobile/src/lib/api.ts now sends JSON.stringify({}) for
methods with a body slot when no body is provided, instead of sending
undefined with content-type: application/json.
- Fixes scan start crash (POST /v1/scans/:id/start) and latent
resend-verification crash (POST /v1/auth/resend-verification).
- Server strictness left intact; uploadImage unchanged.
- Added unit tests for GET/HEAD/POST/PUT body behaviour.
