Restructure catalog to root categories + collapsible groups

- Migration: replace 45 leaf categories (diag.scan, engine.mech…) with
  17 root categories (diag, engine…); update labors.category by taking
  the prefix before the first dot; delete the leaf LaborCategory rows
- ImportLaborCatalogCommand: rewritten to use root categories directly
  so future imports go to the right level from the start
- LaborResource: add ->collapsible() to groups so user can collapse/
  expand each category section to see only headers or only one group
- entrypoint.sh: remove one-time catalog import (was already done)
