feat(testing): verify indexed keys in event assertions

Add verification of indexed keys in event assertions to ensure proper event
structure testing. This change:

• Adds verify_indexed_keys() function to check event key matching
• Implements key verification in is_emitted() alongside data matching
• Updates EventSpyQueue to handle ordered event assertions

Hi @ericnordelo , just following up on this. Would appreciate it if you could take a look at the PR when you have some time. Happy to address any feedback. Thanks!

Hey. Thanks again for taking the time. I will review it it early this week. Thanks for your patience!

[turkaturki]

Thanks for the feedback! @ericnordelo I understand your point about that approach potentially being redundant. I've updated the implementation and changed the approach based on your comment. Could you please take a look and let me know if I'm heading in the right direction or if there’s anything else I should adjust?

[turkaturki]

Thanks for the clarification! I've reverted is_emitted to its original form.

The function looks good @turkaturki. Note that we still need to use it in our tests to resolve the issue. We should add it to our event helpers with the appropriate keys for each event in each different module.
