- Sistema de propiedades: modal add-property con autocomplete y selector de ícono
- category.page rediseñado: selector de propiedad, fotos (Capacitor Camera), sin fecha/precio
- Modal postulate-offer: proveedor propone 2 fechas requeridas + monto con validación de cuota mínima
- viewsuppliers: chips de ordenamiento frontend (fecha, precio, certificados)
- hire.page: selección de fecha (date_1/date_2) antes de contratar; selected_date en contracts/create y contracts/coupon
- Modal contract-discussion: chat de burbujas para contratos activos
- contracted.page: botón de chat por contrato
- pending.page: botones cancelar y repostular por postulación
- Modal repostulate: pre-llena categoría/propiedad, archiva original como perdido y crea nueva con related_postulation_id
- current.page: temporizador de expiración basado en time_created (1000 min), oculta expiradas
- ichamba.service: nuevos métodos properties, cancelPostulation, contractDiscussion, updated signatures
