/**
 * api/campaigns.js — Client for Hub /campaigns endpoints.
 *
 * Mirrors services/targo-hub/lib/campaigns.js. All gift-campaign requests
 * go through the Hub which handles ERPNext auth + Mailjet send + SSE
 * progress broadcast.
 *
 * Functions:
 *   parseCsvs({ map_csv, giftbit_csv, multi })   → preview matched send list
 *   createCampaign({ name, params, recipients }) → save + return id
 *   listCampaigns()                              → summaries
 *   getCampaign(id)                              → full detail
 *   updateCampaign(id, patch)                    → edit recipients/params
 *   sendCampaign(id)                             → fire background worker
 *   campaignSseUrl(id)                           → SSE URL for live updates
