Staff Create Pet: add tooltips to the published and paused applications toggles

[kasugaijin]

These two toggles might not be intuitive to understand what they are for, so it would be good to add an icon and tooltip description for each. See an example of a tooktip in action on our theme here (for password strength): https://geeksui.codescandy.com/geeks/pages/security.html

Application Paused: 'If applications are paused, the public can see the pet but cannot submit an adoption application.'
Published: 'If a pet is published it is visible to the public.'
