Victor Kuznetsov d4d9429328 feat(identify): attribute Canva and BytePlus C2PA; fix BytePlus->Adobe mislabel

Mining the local production corpus (25,725 imgs) surfaced two AI vendors signing
C2PA that the registry missed:
- Canva (Magic Media) signed "Canva" + trainedAlgorithmicMedia -> detected AI but
  no platform attributed (disproves the old "Canva exports strip C2PA" assumption).
- BytePlus (ByteDance international: Seedream/Seededit) signs "Byteplus Pte. Ltd.";
  the bare volcengine needle missed it, so its output was mis-attributed to "Adobe
  Firefly" via an incidental "Adobe XMP" string the fallback byte-scan picked up.

Adding both to C2PA_AI_VENDORS lets the clean manifest issuer attribute them
directly. Corpus re-run: 16 platform changes, all improvements (3 Adobe->ByteDance
fixes, 4 None/TC260->ByteDance, 9 None->Canva), 0 regressions. An attempted
signer-based attribution fallback was measured and dropped: it regressed 18 images
(friendly ByteDance label -> raw Chinese cert org; IPTC tool name pre-empted).
