Make version/build number clickable to check for updates

Split the footer version display into two parts: the app version/build number is now a clickable button that triggers an update check (with tertiary label color to blend in visually), while the llama.cpp version remains static text.

Also fixed the update check implementation to use SPUStandardUpdaterController's proper checkForUpdates(_:) method instead of accessing the underlying updater directly, which follows Sparkle 2.8 best practices for user-initiated checks.
