Changed namespace to EnvelopeGenerator.API.Controllers. Updated _mLocalizer and its constructor parameter to use IStringLocalizer<Resource> instead of IStringLocalizer<Model>. Removed unused EnvelopeGenerator.CommonServices using directive.
Deleted dotnet-tools.json (dotnet-ef config) and IIS publish profiles for .NET 7 and .NET 9 (IISProfileNet7Win64.pubxml, IISProfileNet9Win64.pubxml) to clean up unused deployment and tooling files.
