[#SIRH] Récap salaire: exclure les salariés sans contrat sur le mois

Le récap listait tous les employés sans filtrer le contrat: un salarié au
contrat terminé (ex. Marine, fin 26/02) apparaissait sur le récap de juin.
Ajout du filtre hasContractInRange (même règle que l'impression absences) sur
la période [from, to] du mois imprimé.

4 tests ajoutés. Vérifié sur données prod (Marine + 6 autres contrats terminés
exclus du mois de juin, 39 salariés contractés conservés).
