Add --diagnose flag, remove obsolete helper scripts, fix docs

- Add --diagnose option that shows all PCI paths, storage controllers,
  block devices, and validates current mappings. Replaces the separate
  diagnose-drives.sh script.
- Remove diagnose-drives.sh (incorporated into --diagnose).
- Remove get-serials.sh (redundant with SMART data in main table).
- Remove test-paths.sh (referenced non-existent 0c:00.0 controller).
- Remove todo.md (massively outdated).
- Fix storage controller text overflowing box borders in large1 and
  micro layouts by adding truncation (%-69.69s, %-57.57s).
- Fix chassis name to CX4712 in README.
- Update server mapping statuses from "Requires mapping" to actual
  partially-mapped states.
- Add ⚠ health indicator to README output column docs.
- Update Claude.md metrics to match current state.
