Add Directory.Packages.props copy to all Dockerfiles

The Docker builds were failing because the centralized package version
management file (Directory.Packages.props) was not being copied into the
build context. This file is required for NuGet to resolve package versions
in projects that don't specify explicit versions.

Updated all Dockerfiles to copy Directory.Packages.props before running
dotnet restore:
- Apis/api/Dockerfile
- Apis/cv-matcher-api/Dockerfile
- Apis/rag-api/Dockerfile
- Jobs/cv-cleanup-job/Dockerfile
- Jobs/cv-search-job/Dockerfile
- web/Dockerfile
