Refactor Linux application handling in webview

This update introduces a LinuxOptions struct for Linux-specific application configurations and refines webview for Linux. The 'windows' map has been renamed to 'windowMap' to avoid confusion. Moreover, a method to unregister Windows has been added to ensure the Linux application automatically quits when the last window closes, unless explicitly disabled in the new LinuxOptions structure. Reset Window position after hiding. Some debug output has been removed.
