fix(dell): match DPU HTTP boot option by name prefix, not exact equality

set_boot_order_dpu_first / is_boot_order_setup / machine_setup_status all
compared the expected boot option name "HTTP Device 1: {DeviceDescription}"
for *exact* equality against the boot option display_name. On Dell iDRAC the
real name has a suffix, e.g.:

  "HTTP Device 1: NIC in Slot 40 Port 1 Partition 1 - Nvidia Network Adapter - C4:70:BD:2C:3C:0A - IPv4"

so exact ==/!= never matches: set fails with MissingBootOption, and the
verify path (is_boot_order_setup) reports the order unconfigured. Downstream
(NICo) this wedges host provisioning at SetBootOrder/CheckBootOrder.

Match by prefix (starts_with) in all three places. Verified on a live
BlueField-3 + Dell PowerEdge XE9680 (iDRAC): the set fix advanced the state
SetBootOrder -> CheckBootOrder, and the verify fix clears CheckBootOrder.
