Support incremental sync intervals faster than 15 minutes

German Martinez
Port’s incremental syncs currently run no more often than every 15 minutes, so changes in source systems can take up to a quarter hour to appear in the catalog. Teams that rely on Port as a near-real-time source of truth, especially during incidents and deployments, need fresher data. Live events are not an option for us, and an organizational constraint currently prevents us from using webhooks, so polling at shorter intervals is the practical path for now. We propose allowing sub-15-minute intervals (for example, 5 minutes) per integration
