Pull request overview

Updates the .NET sample documentation/comments to consistently refer to Microsoft Foundry (replacing Azure Foundry / Azure AI Foundry) across dotnet/samples/, aligning sample wording with updated product naming while leaving runtime behavior unchanged.

Changes:

• Replaced “Azure Foundry” / “Azure AI Foundry” wording with “Microsoft Foundry” across sample READMEs, comments, and YAML metadata.
• Updated section headings and environment-variable descriptions to reflect “Microsoft Foundry project” terminology.
• Kept existing Learn URLs unchanged (per PR description), only adjusting display text.
