Integrated DevExpress Blazor components and added a responsive,
modern UI for the sender dashboard. Replaced placeholder content
with a functional layout, including a grid-based envelope viewer
with filtering, pagination, and detailed row templates.
Added status badges, progress indicators, and a sender action
bar with buttons for creating, editing, deleting, refreshing
envelopes, and logging out. Introduced loading and error
handling states for better user experience.
Refactored data loading with `LoadEnvelopesAsync` to fetch and
categorize envelopes. Added methods for envelope management
and logout functionality. Improved state management and removed
unused code. These changes lay the groundwork for future
enhancements.
Added an `[Authorize]` attribute with the "Sender" policy to restrict access to the `EnvelopeSenderPage.razor`. Updated the page title to "Umschläge" and added placeholder text for data loading.
Injected `EnvelopeService` and `IJSRuntime` to fetch and log active and completed envelopes. Introduced `_activeEnvelopes` and `_completedEnvelopes` fields to store fetched data. Configured `JsonSerializerOptions` for consistent JSON handling.
Implemented `OnInitializedAsync` to fetch data asynchronously, log results to the console, and handle errors gracefully.
