feat: core entities, infrastructure, and lead repositories

- 25 domain entities mapped from original Datos/ classes
- 4 enums (EstadoLead, TipoPago, TipoDocumento, TipoDescuento)
- DTOs for Lead, Auth flows
- 6 repository interfaces
- VentasDbContext with EF Core + Npgsql
- LeadRepository (command SPs) and LeadQueryRepository (query SPs) with Dapper
- Program.cs with JWT auth, CORS, DI setup
- appsettings.json with connection string
- .gitignore for bin/obj/node_modules
- ROADMAP.md for daily progress tracking

+## Bitácora Diaria
+
+| Fecha | Fase | Qué se hizo | Siguiente paso |
+|-------|------|-------------|----------------|
+| 2026-07-07 | F1 | Entities (25), Enums (4), DTOs, Interfaces (6), DbContext, LeadRepository, LeadQueryRepository, DI setup, appsettings | Resto repos (Contrato, Cotizacion, Alumno) + Controllers |
+| | | | |
+| | | | |
+
+---
+
+## Próximos Pasos Inmediatos
+
+1. ~~Completar `Ventas.Core/Entities/`~~ ✅
+2. ~~Configurar `VentasDbContext`~~ ✅
+3. ~~Crear `LeadRepository` + `LeadQueryRepository`~~ ✅
+4. **Agregar referencia Infrastructure a Ventas.API** ✅
+5. **Configurar JWT + CORS + DI en Program.cs** ✅
+6. **Actualizar `appsettings.json`** con connection string ✅
+7. **Seguir repositorios** por prioridad: Contrato → Cotizacion → Alumno → Usuario → Auth
+8. **Crear Controllers** (empezar con AuthController + LeadController)
+9. **Probar compilación** con `dotnet build`
