Update funds recipents form

[marineb]

What's in this PR?

• didn't complete the org / individual toggle at the top. I wasn't sure how to extend the target area of the radio button with ember
• I know my class names and the general markup structure aren't great :(
• suggested some language changes (not sure what the requirements are here, just thought i'd share some diff options)
• in the address section, I was wondering if all these fields are required for cc processing? (or could you have only the zipcode instead?)

@marine this is just for accepting donations, not for paying. These are strict requirements under know your customer laws and Stripe's needs.

Good work so far. I'll take over for now, since I'm available, and it's high priority.

Thank you @begedin. Happy to style the radio buttons later. Lmk!

This ought to be good to review. The form has all the fields and submits correctly based on recipient type. The two integration tests I wrote ensure that.

There are minor details on how the radio buttons look (wasn't sure about correct margins/paddings), but overall, it follows the provided designs, I think.
