Add modal props & update RequestCard/tests

Extend AudiobookDetailsModal props with onStatusChange, onIgnoreChange, hideRequestActions, hasReportedIssue, and aiReason. Stop forcing hideRequestActions when opening the modal from RequestCard so the modal can control whether request actions are shown. Add tests: verify admin sticky footer/status pill in AudiobookDetailsModal for pending requests, and add a RequestCard test that mocks AudiobookDetailsModal to assert the modal receives isOpen, asin and that hideRequestActions is not forced. Reset the new mock between tests.
