feat : agence d'intérim sur les contrats INTERIM + renommage Types d'absence en Types de statut + colonne Absence en Statut

- Nouvelle entité InterimAgency (table interim_agencies, API lecture seule)
- Sélecteur agence conditionnel dans les formulaires création employé et ajout contrat
- Affichage "Intérim (NomAgence)" sur la liste employés et l'historique contrat
- Date de fin obligatoire côté frontend pour CDD et INTERIM (aligné backend)
- Renommage "Types d'absence" → "Types de statut" (sidebar, page, titre)
- Renommage en-tête "Absence" → "Statut" sur les vues jour heures et conducteurs
