Add distributed cache, localization, and infra services

- Add DigitalData.Core.API and SQL Server distributed cache dependencies
- Register EnvelopeGenerator.Application project reference
- Configure distributed SQL Server cache and memory cache
- Register infrastructure, application, and user management services
- Set up EF Core with SQL Server and detailed logging
- Enable localization with configurable supported cultures
- Improve modularity and extensibility of service registration
