Add login route and enhance login page functionality

Browse Source 
Added a new `/login/{**catch-all}` route in `yarp.json` for the `receiver-ui` cluster. Updated `Login.razor` with a modernized UI, including a gradient header, improved error handling, and a toggle for password visibility. Integrated `AuthService` for API-based login validation.

Refactored `Login.razor` logic to handle login outcomes (`Success`, `InvalidCode`, `NotFound`, `Error`) using the new `EnvelopeLoginResult` enum. Added `LoginEnvelopeReceiverAsync` method in `AuthService` to handle login requests via `POST /api/Auth/envelope-receiver/{key}`. Improved code maintainability and user experience.
