Add dynamic typing animation to homepage description
Introduced a dynamic typing effect for the homepage description using the `Typed` library. Replaced hardcoded description text in `Index.razor` with a dynamically rendered `<span>` element. Added a constant for the description text and implemented `OnAfterRenderAsync` to invoke the typing animation on first render. Included the `typed.umd.js` library in `index.html` and updated `receiver-signature.js` with a `startTyped` function to support typing animations. Registered `startTyped` in the public API for external use. Enhanced the user experience with dynamic content rendering and improved maintainability by centralizing the description text. Also added a new theme file for improved styling.
