feat: integrate EnvelopeGenerator infrastructure, DB context, and services

- Added references to EnvelopeGenerator.Application, Infrastructure, and EF Core.
- Configured DB context with SQL Server connection string from configuration.
- Registered EnvelopeGenerator services and infrastructure with dependency injection.
- Preserved warnings suppression for obsolete members.
- Structured DI registration under a dedicated region for clarity.
