Fix ASCII art rendering and correct bay 1 mapping

Fixed issues:
- ASCII art boxes now render correctly with fixed-width layout
- Corrected bay 1 mapping: ata-2 -> bay 1 (sdh SSD confirmed)
- Adjusted mobo SATA port mappings based on physical verification
- Simplified layout to use consistent 10-character wide bay boxes

Bay 1 is confirmed to contain sdh (Crucial SSD boot drive) which maps
to pci-0000:0d:00.0-ata-2, so the mapping has been corrected.
