Initial commit: HOA Financial Intelligence Platform MVP

Multi-tenant financial management platform for homeowner associations featuring:
- NestJS backend with 16 modules (auth, accounts, transactions, budgets, units,
  invoices, payments, vendors, reserves, investments, capital projects, reports)
- React + Mantine frontend with dashboard, CRUD pages, and financial reports
- Schema-per-tenant PostgreSQL isolation with JWT-based tenant resolution
- Docker Compose infrastructure (nginx, backend, frontend, postgres, redis)
- Comprehensive seed data for Sunrise Valley HOA demo
- 39 API endpoints with Swagger documentation
- Double-entry bookkeeping with journal entries
- Budget vs actual reporting and Sankey cash flow visualization
