Add --device flag to ds install command

[hiroTamada]

Summary

• Adds --device flag to lw ds install to specify the boot device (e.g., SATA_SAS, NVME, or a disk set ID)
• NVMe-only servers (like HP DL385 G11) fail with "Requested boot device SATA_SAS is not present" because the API defaults to SATA_SAS when no device is specified
• The Leaseweb API already supports this parameter — we just weren't passing it through

Usage

lw ds install <server-id> --os DEBIAN_12_64BIT --hostname my-host --device NVME

Test plan

• lw ds install --help shows the new --device flag
• Verified against Leaseweb API docs: device field supports SATA_SAS, NVME, or disk set IDs
• Successfully used device: NVME via direct API call to install on NVMe-only HP DL385 G11 servers

Note

Low Risk
Low risk: adds an optional CLI flag that only affects ds install requests when explicitly provided, forwarding an extra field to the existing API call.

Overview
Adds an optional --device flag to lw ds install and forwards it as device in the /bareMetals/v2/servers/{id}/install payload, allowing callers to choose the boot device (e.g., SATA_SAS, NVME, or a disk set ID) instead of relying on the API default.

Risk assessment: Low risk.

Evidence from diff:

• Single file changed: pkg/cmd/dedicated_servers.go
• Small, scoped change (+7/-0): adds one CLI flag (--device) and conditionally forwards it into existing install payload
• No infrastructure/auth/permission/schema/shared-platform changes
• No broad refactor or cross-cutting behavior changes

Decision:

• Code review assignment not required for Low risk under policy
• Approving this PR
