chore: prune dead code and refresh stale docs

- Delete 4 empty, unreferenced orphan scripts in dev/scripts/
  (find_databricks_workspace, scrape_bls_data, generate_bls_express,
  test_databricks_connection).
- Remove the unconditionally-skipped TestFixFields.test_runs in
  tests/zot/test_ops.py — fix_fields is already exercised end-to-end by
  test_ops_deep.py::test_fix_fields_remap_and_delete (which builds the
  itemTypeFieldsCombined view the stub said it needed).
- Remove the empty .github/workflows/ orphan left from the Gitea move
  (CI lives entirely in .gitea/workflows/).
- Drop two dead locals in dev/scripts (F841): an unused authors_section
  loop and a `tags` assignment immediately overwritten by fresh_tags.
- docs/docs/intro.md listed only 9 of 17 modules — sync the packages
  table and src/ tree with the actual module set.
