Fix PCI path mappings and line endings for compute-storage-01

Hardware discovered:
- LSI SAS3008 HBA at 01:00.0 (bays 5-10 via mini-SAS HD cables)
- AMD SATA controller at 0d:00.0 (bays 1-4)
- NVMe at 0e:00.0 (M.2 slot)

Changes:
- Updated SERVER_MAPPINGS with correct PCI paths based on actual hardware
- Fixed diagnose-drives.sh CRLF line endings (was causing script errors)
- Updated README with accurate controller information
- Mapped all 10 bays plus M.2 NVMe slot
- Added detailed cable mapping comments from user documentation

The old mapping referenced non-existent controller 0c:00.0. Now uses
actual SAS PHY paths and ATA port numbers that match physical bays.
