Complete rebrand cleanup: remaining env vars and references

Fix STEGASOO_* env vars → FIELDWITNESS_* and VERISOO_* → FIELDWITNESS_*
across stego module, attest module, and frontends. Wire format
identifiers (VERISOO\x00 magic bytes, STEGASOO-Z: QR prefixes)
intentionally preserved for backwards compatibility.
