fix: rewrite Synology API to match actual DSM field names

- Volume sizes are in vol.size.total / vol.size.used (nested object)
- Added disk info parsing (name, model, status, temp, isSsd)
- Added SYNO.Core.System.Utilization for CPU/memory stats
- Response now returns {volumes, disks, utilization} matching widget interface
