Prevent loss of recording when closing main window

[cristianoventura]

Currently, if a recording is in progress and the user closes the main window, the browser window (where the recording takes place) is also closed. This causes the ongoing recording to be lost without any warning or confirmation.

If a recording is in progress and the user attempts to close the main window, we should prompt the user with a confirmation dialog.

We already do something similar for the generator, so we can probably reuse this implementation.

k6-studio/src/views/Generator/Generator.tsx

Lines 94 to 101 in f1f035a

	useEffect(() => {
	return window.studio.app.onApplicationClose(() => {
	if (isDirty || blocker.state === 'blocked') {
	setIsAppClosing(true)
	return
	}
	window.studio.app.closeApplication()
	})

The main process already knows if the client side requested the app to be closed.

k6-studio/src/main.ts

Lines 237 to 241 in f1f035a

	mainWindow.on('close', (event) => {
	mainWindow.webContents.send('app:close')
	if (currentClientRoute.startsWith('/generator') && !wasAppClosedByClient) {
	event.preventDefault()
	}
