Refactor Profile entity and update property constraints

Renamed `Profile` to `CfgProfile` across the codebase for clarity and consistency. Updated property constraints in `CfgProfile.cs`, `ProfileHistory.cs`, and `ProfileSqlJob.cs` to include maximum length validations. Changed navigation properties in `CfgProfile.cs` to use `IEnumerable` and made them nullable. Updated `ForeignKey` attributes in `ProfileHistory.cs` and `ProfileSqlJob.cs` to reference `CfgProfile`. Improved property descriptions for better documentation.
