client side validation for url and status report fields

[haszari]

When you submit a HappyChat request for WooCommerce.com, a site url and status report are required fields. The format of these fields is tricky and it could be frustrating for users as the server-side validation takes time, and blocks the support request. Adding some basic client-side validation could make the experience of reaching out for help a little smoother.

How to reproduce

• Get HappyChat up in WooCommerce mode (this may apply to other modes, not sure if these fields are woo-specific).
• You're feeling stressed out, need some help, and in a hurry. Type some random characters in the url and status report fields so you can get your support request underway.
• Click Submit Request ..
• .. wait ..
• System Status Report is invalid or unsupported or other computer says no responses, dang it!
