fix(legacy-mcu1): declare matched initramfs firmware and return probe errors

Backport the issue #117 loader fix, declaring the 80 firmware/configuration files actually shipped by legacy-mcu1 rather than the main firmware set. Preserve the existing V3 binaries and loader profiles.

All three modules build against Linux 6.17 headers; inventory, built-module metadata and extracted probe error/re-enumeration regression checks pass. Hardware boot validation remains pending.
