Introduced a `DbConnection` constructor in `JobRunnerDbContext`
for Entity Framework 6 to enable in-memory testing with the
Effort library. Added conditional compilation to support both
.NET Framework 4.8 and .NET 8.
Implemented `AddInfrastructureInMemory` in `DependencyExtension`
to register services with in-memory databases:
- For .NET 4.8, uses Effort's transient connection.
- For .NET 8, uses EF Core's in-memory provider.
Registered AutoMapper in both methods for object mapping. Added
`EntityMappingProfile` to define AutoMapper configurations,
enforcing explicit DTO-to-entity mappings. These changes improve
testability and maintainability across .NET versions.
Introduce `JobRunnerDbContext` to support both EF6 (.NET 4.8)
and EF Core (.NET 8) using conditional compilation. Add `DbSet`
properties for `CfgProfiles`, `ProfileSqlJobs`, and
`ProfileHistories`. Provide constructors for both frameworks
to handle connection strings or options. Ensure compatibility
with multiple runtime environments.
