Refactor Drive Atlas with modular chassis templates and PCI path mapping

Major improvements:
- Separated chassis types from server hostnames for better reusability
- Implemented template-based layout system (10bay, large1)
- Renamed medium2 to compute-storage-01 for clarity
- All three Sliger CX471225 servers now use unified 10bay layout
- Added comprehensive PCI path-based drive mapping system
- Created diagnose-drives.sh helper script for mapping new servers
- Added DEBUG mode for troubleshooting drive mappings

Technical changes:
- Replaced DRIVE_MAPPINGS with separate SERVER_MAPPINGS and CHASSIS_TYPES
- Removed spare-10bay layout (all Sliger chassis use same template)
- Improved drive detection and SMART data collection
- Better error handling for missing drives and unmapped servers
- Cleaner code structure with sectioned comments

Documentation:
- Complete rewrite of README with setup guide and troubleshooting
- Added detailed todo.txt with action plan and technical notes
- Documented Sliger CX471225 4U chassis specifications
- Included step-by-step instructions for mapping new servers
