feat: comprehensive KanzlAI-mGMT system roadmap

Full system vision document covering 23 features across 4 priority tiers:
- P0 (must-have): audit trail, conflict checks, roles/permissions,
  notifications, time tracking, RVG calculator, invoicing, DATEV export
- P1 (should-have): document templates, beA integration, full-text search,
  Wiedervorlagen, email integration, reporting
- P2 (differentiator): patent family tracking, claim charts, UPC case law
  intelligence via mLex, AI document drafting, AI strategy analysis
- P3 (nice-to-have): client portal, PWA, multi-language, EDA

Includes data model designs (24 new tables), API specifications,
implementation phases, competitive analysis, and risk register.
