Add refund request flow from workorder payments

Add a button in the charges/payments area of the workorder that starts a refund or check request flow.

The request should prefill the necessary fields from the workorder and require the requester to enter the reason for the refund. For the payee field, the requester should be able to either use the client name from the workorder or enter a different payee and explain why it differs.

Instead of opening the existing accounting check request form, the preferred approach is a modal in Attik that sends the required data into the accounting system used for check requests.

Additional transcript context

• The transcript clarified that the refund modal should not imply that a refund is actually being issued just because someone fills it out; wording such as issue partial refund may be misleading for fast-moving operations teams and new acquisitions.
• The flow should capture mailing address details directly in the modal because finance needs that information to cut a check.
• The team also called out invoice number and similar order-linked details as part of the information finance needs.
• A preferred version of this flow would send the request directly to finance from the modal rather than forcing a separate manual form submission.
