Reduce CoreData save frequency to lower CPU on Catalyst · 25e2585

ChargeInsightsStore was saving every 5s (aggregated sample) and 15s (session state), causing a continuous CloudKit WAL checkpoint loop and high CPU. Increased intervals to 30s and 60s respectively — the 12s sample bucket makes sub-bucket saves redundant, and a 60s session flush is sufficient for a multi-hour charge.
