fix(dell): support extended HTTP boot option names

[williampnvidia]

Summary

• recognize both legacy exact Dell HTTP boot-option names and newer names with a " - "-delimited adapter/MAC/protocol suffix
• use one bounded matcher in machine_setup_status, set_boot_order_dpu_first, and is_boot_order_setup
• prevent false prefix matches such as Partition 1 matching Partition 10
• add table-driven regression coverage for legacy, extended, and non-matching names

Testing

• cargo fmt --check
• cargo clippy --locked --all-targets --all-features --workspace -- -D warnings
• cargo build
• cargo test --locked -- --test-threads=1
• focused test_dell integration test
• focused test_dell_multi_dpu integration test

Fixes #101.

Related: #93. This is a draft fallback for the existing fix; only one implementation should be merged.
