chore(legacy): muta proiectul Visual FoxPro in legacy-vfp/

Codul VFP original (ROAAUTO) era doar de testare/proba si nu se mai dezvolta.
Mutat in legacy-vfp/ (sursa .prg, proiect .pjx/.PJT, date .DBF/.CDX/.FPT,
test-comenzi.xml). Actualizat caile DBF default in tools/import_dbf.py si
referinta din tests/test_import_dbf.py. Adaugat legacy-vfp/README.md.
