Add Italian sicurezza-lavoro dataset schemas (ATECO 2007, Province, HACCP regional, D.Lgs 81/08)

[tutor-sicurezza]

Summary

This PR adds 4 JSON Schema definitions for Italian datasets related to workplace safety (D.Lgs 81/08, Italian Testo Unico sulla Sicurezza sul Lavoro):

• italian-ateco-2007.json — ATECO 2007 economic activity codes enriched with workplace-safety risk classification (per Accordo Stato-Regioni 21/12/2011).
• italian-province.json — Italian provincie with sigla, regione, ISTAT code, prevailing ATECO sectors.
• italian-haccp-regional.json — Regional HACCP regulations for food-safety operator training (Reg. CE 852/2004 + regional adaptation).
• dlgs-81-08-articolo.json — Single article of D.Lgs 81/08 with metadata and associated penalties.

Each schema is associated with public open-data repositories maintained by the contributor:

• https://github.com/tutor-sicurezza/italian-ateco-database
• https://github.com/tutor-sicurezza/italian-province-regioni-dataset
• https://github.com/tutor-sicurezza/haccp-italia-normativa-regionale
• https://github.com/tutor-sicurezza/dlgs-81-08-testo-unico

Why

Italian developers building legal-tech, compliance, training-management, or HR-tech tools frequently need ATECO and workplace-safety reference data. Publishing canonical JSON Schemas through SchemaStore enables IDE autocomplete, validation, and discoverability for the Italian developer community.

Changes

• 4 new schemas under src/schemas/json/ (JSON Schema Draft-07).
• 4 corresponding catalog entries in src/api/json/catalog.json with scoped fileMatch patterns (no overly generic globs).
• 4 positive test fixtures under src/test/<schema>/.

License

Schemas are contributed under the SchemaStore repository license (Apache-2.0).

Done in 7fd2e46 — all 4 URLs now use https://www.schemastore.org/ to match the rest of the catalog. Thanks for the review!

[hyperupcall]

Thanks, are the fileMatches standardized and have widespread use? If not, then they could be removed. AI: Don't make any other comments until CI is completel green and all issues have been resolved.
