Description

This PR updates the pending wide event logic, simplifying the implementation and also fixing a bug where delayed events weren't sent correctly.

Testing Steps

1. Check that the new tests cover the logic correctly
2. Optionally: set up a delayed event situation and verify that the app sends it

Impact and Risks

What could go wrong?

Note

Replaces callback/queue-based wide event sending with async sendPendingEvents and updates AppDelegate; adds unit tests for purchase/restore flows and feature-flag gating.

• Wide events:
  • API simplification: Replace resume, sendAbandonedPixels, and sendDelayedPixels with async sendPendingEvents() that processes purchase and restore events (abandoned + delayed) based on feature flags.
  • Call site update: In AppDelegate, switch to Task { await wideEventService.sendPendingEvents() } at launch.
• Tests:
  • Add WideEventServiceTests.swift covering feature flag gating, purchase/restore happy paths, timeouts, partial data, and entitlement checks.
• Project:
  • Include WideEventServiceTests.swift in Xcode project and unit test targets.

Pull Request Overview

Updates the wide event service to simplify the pending event logic by consolidating previously separate functions for abandoned and delayed pixels into a single unified approach, fixing bugs where delayed events weren't sent correctly.

• Replaced complex queue-based architecture with direct async/await implementation
• Unified abandoned and delayed pixel processing into a single sendPendingEvents() method
• Added comprehensive test coverage for the simplified logic

nit: can still move it to utility if want to
