ci: optimize test performance — from ~3h to 3.5s

- Lazy-load tesseract.js only in OCR route (skips 30MB WASM download)
- Conditional tracing.js import (skip OTel gRPC in test mode)
- Remove unused barcode-detector import
- Add testTimeout/openHandlesTimeout to jest.config.js
- Add --forceExitTimeout=30000 to test script
- Split CI test jobs into parallel workflows (backend/frontend/mobile)
- Add timeout-minutes: 15 to all test jobs
- Use npm ci --ignore-scripts + selective native rebuild
