feat(pdf-burner): integrate repository to fetch envelope annotations

- Added repository access to retrieve signatures and their annotations for a given envelope.
- Updated `BurnInstantJSONAnnotationsToPDF` to accept `envelopeId` and load elements from the database.
- Updated imports to include `DigitalData.Core.Abstractions` and Entity Framework references.
