Address review round 2 (westey-m)

- Remove unnecessary Microsoft.Agents.AI.OpenAI and Azure.AI.OpenAI
  from Foundry sample csproj files (AF sections use AIProjectClient only)
- Remove unused 'using OpenAI.Responses' from Foundry .cs files
- Rename SemanticKernelAIAgentThread.cs -> SemanticKernelAIAgentSession.cs
- Rename SemanticKernelAIAgentThreadTests.cs -> SemanticKernelAIAgentSessionTests.cs
- Apply dotnet format
