Reorder inputs for URL Shortner

[n8thantran]

The current ui looks like this:

Lets re-order the inputs such that

• the alias is first
• the toggle to make the alias automatic is default unchecked and underneath the alias
• the url input is last
• the ui for the cleezy page is default dark, and has a section like
  bg-gradient-to-r from-gray-800 to-gray-600

lets change the above section to
bg-white dark:bg-gradient-to-r dark:from-gray-800 dark:to-gray-600
