NuGet package dependency

`Microsoft.IdentityModel.Extensions` is a NuGet dependency declared by the Pams API project. It provides shared identity-model support used by .NET authentication and token-processing components. The API uses it indirectly through its authentication configuration and related Microsoft identity packages.

## Usage

```typescript
const response = await fetch("/api/pams/requests", {
  headers: {
    Authorization: `Bearer ${accessToken}`,
    Accept: "application/json",
  },
});

if (!response.ok) {
  throw new Error("Request was not authorized or failed.");
}

const requests = await response.json();
console.log(requests);
```

## AI Coding Instructions

- Treat `Microsoft.IdentityModel.Extensions` as a project dependency; application code should use the configured ASP.NET authentication pipeline rather than calling package internals directly.
- Keep bearer-token handling at API boundaries through standard `Authorization` headers.
- Check related `Microsoft.IdentityModel.*` package versions when changing this dependency to avoid incompatible identity assemblies.
- Do not expose token validation details or authentication errors directly in API responses.
