fix: carousel WhatsApp Web real-time rendering (no F5 needed)

Root cause: WhatsApp Web stores pkmsg as ciphertext first, then decrypts
to interactive. React does not re-render the ciphertext→interactive
transition, requiring F5. When enc type is msg (established session),
Web receives as interactive directly and renders in real-time.

Changes:
- messages-send.ts: re-enable biz node for carousel (CDP evidence from
  Pastorini confirms native_flow v=9 name=mixed + quality_control),
  LID-based addressing for session reuse, blocking tctoken fetch,
  force device-identity, skip bot node for carousel
- messages.ts: interactiveMessage direct (no viewOnceMessage wrapper),
  skip Message.create() for carousel (oneOf corruption), skip ephemeral
  contextInfo for carousel
- messages-media.ts: fix jimp type check (function not object)
- tc-token-utils.ts: dual storage under LID and PN for reliable lookup
