The Power supply and Power Subsystem services now use short, readable item names instead of full Redfish URLs.

Before: Power supply /redfish/v1/Chassis/System.Embedded.1/PowerSubsystem/PowerSupplies/PSU.Slot.1

After: Power supply System.Embedded.1/PSU.Slot.1

The item format is <chassis>/<psu_id> — the chassis identifier (as the device reports it under /redfish/v1/Chassis/<chassis>/...) is kept in the name so PSUs with the same local id on different chassis (blade enclosures, multi-node servers) don't collide.

Similarly, Power Subsystem is now named by its chassis id (e.g. Power Subsystem System.Embedded.1) instead of the full URL.

Other Redfish services (temperatures, drives, volumes, thermal) are unchanged.

Migration required

Rediscover services on affected hosts. Existing Power supply and Power Subsystem services appear vanished after upgrade because their item names change.
