TaskyPad 1.0.2

Add update functionality with UI and version handling

Introduced a new "Update Version" button in the UI with custom styling and hover/click effects. The button dynamically displays when an update is available and allows users to download and apply updates.

Refactored `CheckVersion` to use a persistent `UpdateManager` instance and updated the `AddVersionAppUI` method to handle nullable `Version` objects. Added a `ButtonUpdateVersion_Click` event handler to manage the update process, including user confirmation and button state changes during the download.

Enhanced `UpdateManager` with a `ForceUpdate` method for downloading and applying updates, and added debug-mode support for simulating updates. Updated the project file to increment the assembly version to `1.0.2` and enable Windows Forms functionality.
