Introduced `EnvelopeAuthService` and `IEnvelopeAuthService` to handle server-side authentication for envelope receiver pages. - Registered `IEnvelopeAuthService` as a scoped service in `Program.cs`. - Implemented `EnvelopeAuthService` to validate user authentication and envelope key matching using `IHttpContextAccessor` and JWT claims. - Added methods to retrieve the authenticated envelope key and current user (`ClaimsPrincipal`). - Prioritized `NameIdentifier` claim for envelope key extraction, with fallback to `sub` claim. - Documented the service and interface with XML comments for clarity. This centralizes authentication logic, ensuring reusability and adherence to SSR best practices.
