Replaces shared cluster_key for bundle encryption. Each kiosk gets a
unique 32-byte AES key generated at pairing time:
Server:
- confirmPairing generates randomBytes(32), stores encrypted with
server secret on kiosks.encrypt_key_encrypted column
- Delivers plaintext encrypt_key to kiosk in claim response (one-time)
- generateBundle prefers per-kiosk key over cluster_key for
encryptForCluster (same AES-256-GCM format, different key per kiosk)
Kiosk:
- ClaimResp gains encrypt_key field, stored encrypted at rest
- onvif_events prefers encrypt_key over cluster_key for decryption
- Backward compatible: old kiosks without encrypt_key still use
cluster_key (both delivered at pairing)
Security improvement: compromised SD card only exposes camera passwords
encrypted for THAT specific kiosk, not the entire fleet. Rotate by
deleting + re-pairing the compromised kiosk.
