feat: branch betos — propiedades, oferta de proveedores, chat en contratos y flujo de postulacion renovado

- Sistema de propiedades: tabla, modelo, CRUD API para que el cliente guarde direcciones nombradas
- Postulacion renovada: cliente elige propiedad sin precio ni fecha, sube fotos a GCS/S3
- Proveedores ofertan date_1, date_2 y amount al postularse via pivot; sort por fecha/monto/membresia
- Contratacion: selected_date recibe date_1 o date_2, amount desde pivot (depreca minimun_fee)
- Cancelacion/repostulacion: archive con status=perdido, related_postulation_id para vincular
- Chat en contratos activos: tabla contract_comments, controller, rutas web+API, vista panel, notificaciones bilingues
- PaymentIntent calcula amount desde pivot en vez de recibirlo del front
- getpendingcontracts: sin filtro de tiempo, filtra por status=active, agrega time_created
- Expiracion de postulaciones reducida a 1000 min
