feat(technique) : sous-ressources Contacts / Adresses / RIBs (ERP-135)

Expose les sous-collections du prestataire en #[ApiResource] (POST sur le
parent + PATCH/DELETE/GET unitaires), edition complete par onglet (pas de
POST-only, RETEX M1/M2) :

- ProviderContact : POST /providers/{id}/contacts, PATCH/DELETE
  /provider_contacts/{id} (security technique.providers.manage).
  ProviderContactProcessor : normalisation RG-3.11 (nom/prenom Title Case,
  telephones chiffres, email lowercase) + RG-3.04 (au moins un champ parmi
  prenom/nom/telephone/email, miroir du CHECK chk_provider_contact_name -> 422).
- ProviderAddress : POST /providers/{id}/addresses, PATCH/DELETE
  /provider_addresses/{id} (security technique.providers.manage).
  ProviderAddressProcessor : rattachement parent + cloisonnement d'ecriture des
  sites de l'adresse (RG-3.05 / § 2.13 : site hors user_site -> 422 sur sites).
- ProviderRib : POST /providers/{id}/ribs, PATCH/DELETE /provider_ribs/{id}
  (security technique.providers.accounting.manage). ProviderRibProcessor :
  RG-3.08 (DELETE du dernier RIB sous LCR -> 409).

Tests : ProviderSubResourceApiTest (19 cas) — CRUD chaque sous-ressource, 403
selon permission (Contacts/Adresses=manage, RIB=accounting.manage), 409 dernier
RIB LCR, 422 cloisonnement site adresse. Helpers addContact/addRib/paymentType
ajoutes a AbstractProviderApiTestCase.
