.NET: Hosted agent adapter (#5406)

* Bump preview version to 260420.1 and fix AgentServer package deps

- Bump PackageVersion to 0.0.1-preview.260420.1
- Bump Azure.AI.AgentServer.Core beta.21 -> beta.22 (required by
  Azure.AI.AgentServer.Responses beta.3)
- Replace AgentHostTelemetry.ResponsesSourceName with local constant
  (type made internal in AgentServer.Core beta.22)

* Fix CA1873: guard LogError with IsEnabled check in FoundryToolboxService

Wrap the LogError call with an IsEnabled(LogLevel.Error) guard to satisfy
the CA1873 analyzer rule which flags potentially expensive argument
evaluation when logging is disabled.

* Bumping NuGet version

* Restore conditional versioning, remove dev feed, bump Azure.AI.Projects to beta.1
