Fix PN532 transport and NFC tag handling.

Tighten PN532 framing and NFC access locking so scan, read, write, and raw operations behave reliably on hardware, and correct Classic versus Type 2 tag classification so common cards hit the right code paths. Refresh the embedded web assets and launcher files to match the corrected firmware behavior.
