[Recipient Dashboard] "View" button in payment history should link to on-chain transaction in block explorer

[7maylord]

Description:

In the recipient dashboard's payment history section, the View button currently lacks functionality. To enhance transparency and trust, this button should open the corresponding transaction in a blockchain explorer, allowing recipients to verify their payments on-chain.

Current Behavior:

The "View" button does not do anything

Expected Behavior:

Clicking "View" should open a new tab linking to the block explorer (e.g., Etherscan, PolygonScan) with the specific transaction hash.

Suggested Fix:

• Ensure transaction hash is available in the payment data.

• Update the button to dynamically generate the block explorer URL using the hash.

• Open the link in a new browser tab.
