Abin ToppoandClaude Opus 5.5 5fbd13ba12 Add TPIN reset via OTP, with server-clock countdowns and redacted API logs
- Reset TPIN: empty-body initiate -> OTP -> encrypted new TPIN via
  /tpin/reset/*, from a Services tile, search, and "Forgot your TPIN?"
  on the transfer's TPIN sheet (returns to the same transfer review)
- Handle every documented code: SESSION_INVALID signs out, TPIN_NOT_SET
  offers Create TPIN, CBS customer/account/org refusals stop the flow,
  outages retry from the start, expired or spent OTP/token restarts,
  policy VALIDATION_ERROR stays on the new-TPIN step
- Secrets live in screen state only and are dropped as each step ends
- Countdowns use the envelope timestamp, kept aside by the interceptor,
  so a wrong device clock cannot skew OTP or token expiry
- New TPINs refuse any three-digit run (1235, 5987), for create too
- Dev API logger redacts the session token, OTPs, PINs, encrypted
  payloads and one-time tokens
- Tests: request bodies, RSA-OAEP SHA-256 payload decrypted with Node,
  fresh nonce on key retry, server-clock deadlines, log redaction
