Services - Import

CSV-based import and export of the billable services catalog. Auto-detects the file format: native Sodium exports (rows with a matching Code update the existing service) or Ignition services exports (create-only). Analyze returns editable preview rows; import re-uploads the file with the user's selections and creates/updates services plus deduplicated Service Terms content blocks. Export produces the native format including terms HTML, doubling as the import template. All endpoints are stateless.
