Subject: [PATCH] Add DI support for RecDbContext with configuration options

Introduced a `DependencyInjection` class with an extension
method `AddInfrastructureServices` to register `RecDbContext`
using configurable `DbContextOptions`. Added a `ConfigurationOptions`
class to encapsulate `DbContext` configuration.

Validated that `DbContextOptionsAction` is provided before
registration. Updated `ReC.Infrastructure.csproj` to include
`Microsoft.Extensions.Configuration.Abstractions` for enhanced
configuration support. Added necessary `using` directives.
