Fix charge span leak in the payment service

[ayoisaiah]

Changes

Fix span lifecycle and exception attribution in the payment service charge span.

• Wrap the body of charge() in a try/catch/finally so span.end() is always called, including on validation error paths where the span previously leaked.
• Record the exception and set SpanStatusCode.ERROR on the charge span in the catch block, where the failure actually originates.
• Remove span.recordException(err) from index.js. The gRPC span now only has its status set to ERROR with the error message, avoiding duplicate exception attribution.

Fixes #3275

Merge Requirements

Pull request overview

Fixes OpenTelemetry span lifecycle and error attribution in the payment service so the manually-created charge span is always ended and owns its own exceptions (instead of leaking or attributing exceptions to the parent gRPC span), addressing issue #3275.

Changes:

• Wrap charge() logic in try/catch/finally to guarantee span.end() on all paths and to record exception + ERROR status on the charge span.
• Remove explicit recordException() on the parent gRPC span and set its status to ERROR with the error message to avoid duplicate exception attribution.
