Feat: Auto-close parameter and success animation reset

Related to #478 & #477

Description

Added a new parameter 'autoClose' that defaults to true and will automatically close the payment dialog after a payment is received.

If set to false, the dialog remains open and after 3 seconds, the widget reverts back to the original state so another payment can be made.

Test plan

• Make a payment on dialog it should auto close
• set auto-close to false and try again. It should remain open and you'll see the qr code come back
• The widget should be unaffected by autoclose, but should see the qr reset as well
