fix(ack-pay): preserve original error cause in verifyPaymentRequestToken

[ak68a]

Summary

• Preserve the original JWT verification error as an Error Cause when throwing InvalidPaymentRequestTokenError
• Update the error constructor to accept ErrorOptions

Previously, the catch block discarded the original error (expired token, bad signature, DID resolution failure), making it difficult to diagnose payment request verification failures. The original error is now available via .cause.

Test plan

• All 32 existing ack-pay tests pass unchanged
• Error cause is accessible on caught InvalidPaymentRequestTokenError instances

Walkthrough

Enhanced error handling in payment request token verification by adding ErrorOptions parameter support to InvalidPaymentRequestTokenError constructor and modifying error catching to preserve the underlying error cause when rethrowing.

Changes
