[User Settings] Add new Payments view

Having added four new menu items to the Settings page, we now need to begin linking those menu items to actual pages. This issue pertains to the Payments page.

The Payments view will be displayed when the “Payments” menu item is clicked. It will display a header with a left-facing arrow on the left-hand side, a title, and an X button to close the view on the right-hand side. The view will contain a prompt, a text box with a title and placeholder, and a button with the text Add a Paypal Account

Deliverables

• Clicking on the Payments menu item on the Settings page will route the user to settings/payments via the payments route in ROUTES.js and display the new view
• The text field should contain the value of the nvp_payPalMeAddress onyx key, if it exists.
  • If the key doesn’t exist or is empty, the field should contain a placeholder value Your Paypal username
• Pressing Add Paypal Account will call NameValuePair.Set with the following parameters:
  • name = "expensify_PayPalMeAddress"
  • value = string value of whatever the user entered in the text field.
• Pressing X will close the right-hand modal and route the user back to the last viewed report
• Pressing < should display the main settings view.

I agree with you Nikki. So I think we should just formally propose a P/S for adding a lost-cost growl solution, and implement that separate from this PR. We can work with you to come up with some styling ideas, but let’s decouple that project from this particular step for now.
