+/**
+ * M3 — Repertoire prestataires (ERP-132) : creation de toute la structure BDD
+ * des prestataires sous le nouveau module Technique (jumeau du M2 fournisseur).
+ *
+ * Tables creees :
+ *  - Table principale : provider (formulaire principal + Comptabilite + archive
+ *    + soft-delete + Timestampable/Blamable). PAS d onglet Information.
+ *  - M2M du formulaire principal : provider_category (RG-3.09),
+ *    provider_site (sites du prestataire, RG-3.03 — NOUVEAU vs supplier).
+ *  - Sous-collections : provider_contact (1:n), provider_address (1:n),
+ *    provider_rib (1:n).
+ *  - Jointures de provider_address : provider_address_site (RG-3.05),
+ *    provider_address_contact, provider_address_category.
+ *
+ * Differences vs le M2 `supplier` (cf. spec M3 § 3.1) :
+ *  - PAS d onglet Information : aucun champ description / competitors /
+ *    founded_at / employees_count / revenue_amount / director_name /
+ *    profit_amount / volume_forecast. Le provider est minimal : nom + compta.
+ *  - AJOUT de provider_site (M2M) : sites rattaches au prestataire directement
+ *    sur le formulaire principal (RG-3.03, >= 1). Sert aussi le cloisonnement
+ *    par site (idx_provider_site_site, § 2.13).
+ *  - provider_address SIMPLIFIEE : pas de address_type / bennes /
+ *    triage_provider (specifiques fournisseur). Champs : country / postal_code
+ *    / city / street / street_complement / position + M2M sites/contacts/categories.
+ *
+ * Referentiels comptables NON recrees : tva_mode / payment_delay / payment_type
+ * / bank sont ceux du M1 (FK partagees, zero duplication — spec § 2.3).
+ *
+ * CategoryType PRESTATAIRE NON re-seede : il est cree par ERP-131
+ * (Version20260612080000) avec ses categories de demonstration. Le M2M
+ * provider_category / provider_address_category s appuie sur ce type existant.
+ *
+ * Namespace racine `DoctrineMigrations` (regle ABSOLUE Starseed n°11) et NON
+ * `App\Module\Technique\...` : la migration cree un schema avec FK cross-module
+ * (user, category, site, et les referentiels comptables M1). Avec plusieurs
+ * migrations_paths, Doctrine Migrations 3.x trie par FQCN alphabetique — un
+ * namespace modulaire s executerait avant la creation de user/category/site sur
+ * base vide -> echec des FK. Le namespace racine garantit l ordre par timestamp.
+ *
+ * Style DDL aligne sur le M1/M2 (Version20260605130000) : `INT GENERATED BY
+ * DEFAULT AS IDENTITY` (et non SERIAL), `TIMESTAMP(0) WITHOUT TIME ZONE` (et non
+ * TIMESTAMPTZ, car le TimestampableBlamableTrait mappe `datetime_immutable`).
+ * Garantit que `schema:update` restera un no-op quand les entites arriveront
+ * (ticket ERP-133).
+ *
+ * Decision unicite (alignee Q4 M1 / § 2.6 M2) : unicite metier sur le NOM DE
+ * SOCIETE uniquement (uq_provider_company_name_active, partiel). Pas d index
+ * unique sur siren ni email.
+ *
+ * COMMENT ON COLUMN inline (regle ABSOLUE n°12) : chaque colonne metier porte sa
+ * description ici-meme. Volontairement NON ajoutees a `ColumnCommentsCatalog` /
+ * `makefile test-db-setup` a ce stade : tant que les entites Provider* n existent
+ * pas (ERP-133), `schema:update --force` du setup de test droppe ces tables non
+ * mappees — les referencer dans le catalogue ferait planter
+ * `app:apply-column-comments`. Le catalogue + la ligne `dbal:run-sql`
+ * (uq_provider_company_name_active) seront ajoutes au ticket entites (ERP-133),
+ * exactement comme supplier (ERP-86) apres sa migration (ERP-85). Les 4 colonnes
+ * Timestampable/Blamable reutilisent les textes standardises du catalogue
+ * (`timestampableBlamableComments()`, simple tableau statique sans dependance DB).
