Subject: [PATCH] Refactor scope creation and update namespace imports

Replaced `IServiceProvider` with `IServiceScopeFactory` for async scope creation, updated injected services and usages, switched namespace import from `System.Text.RegularExpressions` to `Microsoft.Extensions.AI`, and simplified the `FormatTokenUsageDetails` method signature to use the unqualified `UsageDetails` type.
