#11522 feat(payments): add a View button that opens the payment's page

Add a View button to the Payments page

What changed

• The Payments page now has a View button, next to Edit.
• Select a payment in the table and click View to open that payment's own page, with all its details.
• The button looks the same as the View button on Received Invoices.
• Anyone who can see the Payments page can use it, not only people who can edit payments.
• If nothing is selected, the button stays disabled.

How to test

1. Go to Accounting → Payments.
2. Select a payment in the table.
3. Click View. The payment's page should open.
4. Use the back link on that page to return to Payments.
