Implements `set_boot_override` for Dell iDRAC by PATCHing the `HttpDev1Uri`-related BIOS attributes via `/Systems/{id}/Bios/Settings`. Returns the BIOS config job ID; callers can DELETE it to cancel before the BIOS reboot if needed.
Worth noting Dell doesn't expose the standard Redfish `Boot.HttpBootUri` property, and also rejects PATCHing `BootSourceOverrideTarget/Enabled` via `/Systems/{id}/Settings` (only `Boot.BootOrder` and `BootSourceOverrideMode` are accepted there). The `HttpDev1Uri` attribute is the Dell-documented path for pinning UEFI HTTP boot URLs.
Verified end-to-end:
- iDRAC9: R760 (BIOS 2.5.4), R760xd2 (BIOS 1.7.5), XE9680 (some).
- iDRAC10: R670 (BIOS 1.7.5).
Integration tests cover both paths:
- dell mockup (`HttpDev1Uri.ReadOnly=false`) exercises the `PATCH` path.
- dell_multi_dpu mockup (`HttpDev1Uri.ReadOnly=true`) exercises the locked path.
Note that there seemed to be some machines that were reporting as being
locked/read-only, even though they didn't appear to be in lockdown. Not
really sure what was going on there, but if for some reason the PATCHing
fails, we'll just return the error (and it will be up to the caller to
decide what they want to do).
