Add NLog configuration and minor property updates

Added a new NLog configuration section in `appsettings.json` to enable structured logging. This includes settings for log file storage, log targets for different levels (Info, Warn, Error, Fatal), and retention policies.

Added the `NLog` property to the configuration. Introduced a new `AddedWho` property with the value `ReC.API`.

Removed and re-added the `FakeProfileId` property without changing its value. No changes were made to `LuckyPennySoftwareLicenseKey` or `RecAction` sections.
