feat: implement ReadEnvelopeReportQuery with handler and repository integration

- Add ReadEnvelopeReportQuery record that returns IEnumerable<EnvelopeReport>
- Implement ReadEnvelopeReportQueryHandler with repository and AutoMapper integration
- Add ThrowIfNotFound property with JsonIgnore and NotMapped attributes
- Integrate IRepository<EnvelopeReport> for data access
- Add NotFoundException when no reports found and ThrowIfNotFound is true
- Configure Entity Framework Core using Microsoft.EntityFrameworkCore
- Add JSON serialization configuration with System.Text.Json
- Update using statements with necessary abstractions and exceptions
