test: extend retry window for synthetic PPE event propagation (#865)

## Summary

- Increased `retry_counter(30)` to `retry_counter(120)` in
`test_actor_push_data_charges_both_events` and
`test_actor_push_data_combined_budget_limit`
- Synthetic events like `apify-default-dataset-item` are computed by the
platform from dataset writes asynchronously — unlike explicit charges
(which hit the charge endpoint directly and reflect immediately), these
take longer to propagate into `charged_event_counts`
- The existing 30-second window was insufficient; 2 minutes gives the
platform enough time

**Failed CI run that triggered this fix:**
