debug(tracking): verbose logging for QGIV.donationComplete

[mohanadft]

Summary

• Adds [T4P DEBUG] console.log statements at every step of the QGIV.donationComplete handler
• Logs: event firing, event.detail, transaction fields (recurring, frequency, status, total), isRecurring calculation, which Plausible event name is sent, and whether plausible is defined

Purpose

Temporary debug PR to diagnose why Plausible events are not firing after donations. Will be reverted once root cause is confirmed.

How to test

1. Go to https://techforpalestine.org/donate?variant=qgiv
2. Open DevTools console
3. Make a test donation
4. Copy all [T4P DEBUG] lines and share
