Add a new dialog class to replace the old one

[sascha-karnatz]

Add a new dialog class with the same signature and the same properties as the old Dialog implementation. The new one is using the shoelace web components and is working with promises to allow the calling method to react to the user input in the dialog.

We need a remote form watcher that handles re-rendering of forms with validation errors

See

alchemy_cms/app/assets/javascripts/alchemy/alchemy.dialog.js.coffee

Lines 104 to 119 in cbef269

	watch_remote_forms: ->
	form = $('[data-remote="true"]', @dialog_body)
	form.bind "ajax:success", (event) =>
	xhr = event.detail[2]
	content_type = xhr.getResponseHeader('Content-Type')
	if content_type.match(/javascript/)
	return
	else
	@dialog_body.html(xhr.responseText)
	@init()
	return
	form.bind "ajax:error", (event, b, c) =>
	statusText = event.detail[1]
	xhr = event.detail[2]
	@show_error(xhr, statusText)
	return
