Handle Partial Success in fulfillMintAllowanceRequest

The fulfillMintAllowanceRequest function processes a batch of TokenMintAllowanceRequest entries and updates the state for each request. If an error occurs during the processing of a request, the function records the error but continues processing the remaining requests. This can lead to a situation where some requests are successfully processed and their state updates are committed to the chain, while others fail, resulting in partial success.

fulfillMintAllowance.ts#L171

Certik finding: MAG-01

Start at fulfillMintAllowance.ts#L171 and trace fulfillMintAllowanceRequest's batch processing and state updates. Reproduce the behavior with a batch containing both successful and failing TokenMintAllowanceRequest entries, then verify the handling of partial success against the MAG-01 finding. Done means the function no longer leaves an unintended mix of committed successes and failures.
