The most significant changes include the addition of the `System.Time…

…rs` namespace to use the `Timer` class, the introduction of a `Timer` object that ticks every second, and the creation of a `TimerElapsed` method that triggers every time the timer ticks. Additionally, the HTML markup for the counter display and button has been removed, and a `Dispose` method has been added to clean up the timer when the component is disposed.

1. The `System.Timers` namespace has been added to the file to use the `Timer` class. This allows the use of a timer in the code.
2. A `PageTitle` has been added to the `@page` directive, providing a title for the webpage.
3. The HTML markup for the counter display and button has been removed, simplifying the user interface.
4. A `Timer` object has been added to the code block, initialized in the `OnInitialized` method. The timer is set to tick every 1 second (1000 milliseconds), auto-reset, and start immediately.
5. A `TimerElapsed` method has been added, which is triggered every time the timer ticks. This method calls the `IncrementCount` method and then invokes `StateHasChanged` to re-render the component on the UI thread.
6. A comment has been added to the `IncrementCount` method to explain that it increments the counter, providing clarity for future code maintenance.
7. A `Dispose` method has been added to clean up the timer when the component is disposed, ensuring efficient resource management.
