-- Migration : suppression des colonnes legacy de servers (consolidées avec les nouvelles)
--   - snapshot_required → requires_snapshot
--   - pre_patch_script  → pre_patch_cmd
--   - post_patch_script → post_patch_cmd
--   - satellite_host    → satellite_url
--   - need_pct          → pct_required
-- ⚠ responsable_nom/email et referent_nom/email sont CONSERVÉS (le backfill
--   vers responsable_domaine_contact_id / referent_technique_contact_id
--   nécessite un fuzzy match qui sera fait dans un script séparé).
-- Idempotent.
