Replaced the old card-based layout in `Index.razor` with a modern, visually appealing home page design. Added a hero header, content section, and call-to-action button for signing documents. Introduced new SVG icons and text elements to enhance the UI.
Removed the `OnAfterRenderAsync` method and automatic redirection logic to simplify user navigation. Added a new stylesheet link for the DevExpress Blazor theme.
Updated `app.css` to support the new design:
- Changed `article` overflow to `overflow-y: auto`.
- Added new classes for layout, buttons, and feature badges.
- Styled the home page with a gradient background, rounded corners, and hover effects.
These changes improve usability, responsiveness, and visual consistency.
Updated the `OnAfterRenderAsync` method in `Index.razor` to navigate to `/receiver` instead of `/reportviewer`. Removed the sidebar containing the `<NavMenu />` component in `MainLayout.razor` and adjusted the `<main>` tag to directly contain the content.
Simplified the `@page` directive by removing redundant entries.
Replaced the introductory section with a centered card layout
featuring a document icon, heading, description, and a
`DxLoadingPanel` with a spinner for redirection feedback.
Removed the "Helpful Resources" section with external links.
Added a new `@code` block to handle redirection logic using
`OnAfterRenderAsync`, which redirects to `/reportviewer` after
a 1200ms delay.
