Add scan progress indicator, payment card detection, and production cleanup

Features:
- Add scanning progress indicator showing current detection step
- Detect payment cards (Visa, Mastercard, Amex, etc.) via PPSE/EMV AIDs
- Show "Payment Device Detected" instead of "Implant Detected" for payment cards
- Hide compatible implants section for payment devices, show conversion instead
- Add Spark 1/2 implant detection via vivokey.co NDEF URL
- Hide conversion card when actual implant is detected

Technical:
- Add DetectionProgressCallback for real-time detection status
- Add payment network AIDs to commands.ts
- Configure babel to strip console.log/warn in production builds
- Add logger utility for development-only logging
