fix(pairing): enforce lockout on approve_code, not just generate_code (#10195) (#21325)
PairingStore.approve_code() didn't consult _is_locked_out(), so after
MAX_FAILED_ATTEMPTS bad approvals the lockout flag was set but a valid
code still got accepted — any pending code (legitimately issued or
attacker-obtained) could be approved during the 1-hour lockout window,
nullifying the brute-force protection.

- gateway/pairing.py: lockout check runs in approve_code() right after
  _cleanup_expired, before the pending lookup. Returns None on lockout.
- tests/gateway/test_pairing.py: test_lockout_blocks_code_approval pins
  the regression — reporter's exact reproducer (generate valid code,
  exhaust attempts with WRONGCODE, try to approve valid code) must
  return None and leave is_approved == False. Also pins recovery: once
  lockout expires, the still-pending code approves normally.
- hermes_cli/pairing.py: _cmd_approve distinguishes the two None cases.
  On lockout, prints 'Platform locked out... clears in N minutes. To
  reset sooner, delete the _lockout:<platform> entry from
  _rate_limits.json' instead of the misleading 'Code not found or
  expired' message. 29/29 pairing tests pass; E2E-verified with
  reporter's exact Python reproducer.
