[Enhancement]: Make Payment Dispute flexible to capture from other payment providers

### Affected Area

None

### Problem Statement

Currently Payment dispute is captured only from Stripe but it would be better if we can capture disputes from other providers as Paypal, Razorpay etc

### Proposed Solution

https://razorpay.com/docs/webhooks/disputes/#list-of-disputes-webhook-events
https://razorpay.com/docs/payments/disputes/dashboard/#view-disputes

Start by reading the existing Stripe dispute-capture flow and the linked Razorpay webhook and dispute documentation. Identify provider-specific assumptions and define the desired provider-neutral behavior, including supported events and completion criteria. No files or tests are named in the issue, so those need to be located before implementation.
