Add legacy SQLAlchemy models mapped from docs/legacy-schema.md: ROLODEX, PHONE, FILES (+R/V), LEDGER, FILESTAT, FOOTERS, EMPLOYEE, STATES, GRUPLKUP, PRINTERS, SETUP, DEPOSITS, PAYMENTS (legacy), TRNSTYPE, TRNSLKUP, PLANINFO, QDROS, PENSIONS (+RESULTS/MARRIAGE/DEATH/SCHEDULE/SEPARATE). Add appropriate FKs and indexes; keep modern models intact.
