/**
 * bf-cameras — query the BF admin for the camera list. Emits a message
 * whose `msg.payload` is an array of cameras:
 *   [{id, name, type, enabled, labels: [...]}, ...]
 *
 * Optional filter: `config.label` — if set, only include cameras carrying
 * that label name (or msg.label override).
 *
 * Use this for populating UI dropdowns or driving "all cameras" loops.
