Update NEON form Styling

[kaylima]

1. Go to: https://freshenergy.staging.wpengine.com/wp-signup.php?new=secure (staging site) and look at the form on the right side.

RESULT: The form looks fine on a desktop, but not great on mobile devices.

EXPECT:

• [x] 1. Move "First Name" etc. (field labels) from the left side to inside the form fields. (See the live site for an example: https://secure.fresh-energy.org/np/clients/freshenergy/account.jsp (bottom of page)
• [x] 2. Make the Sign Up button smaller.
• [x] 3. Add some padding to the right side of the fields and ReCAPTCHA for mobile. (Currently, it's getting cut off on the right side.)
• [x] 4. Make sure that the Donation form on the left side doesn't have white space at the bottom, see here: https://freshenergy.staging.wpengine.com/category/programs/renewable-electricity/
