feat: services, jwt auth, and api controllers

- LeadService with 15 SP calls (CRUD, actividades, pagos, montos)
- UsuarioService for login and profile queries
- JwtService for token generation with claims
- AuthController (login, perfil) with HttpOnly cookie
- LeadController (CRUD, actividades, estado, pago, contacto)
- Registered all services in DI (Program.cs)
