Fix Facebook CAPI Data Gaps

Our Facebook Conversion API is already in place, yet the Event Match Quality score is disappointing because some event-level data is not being captured.

I need someone who deeply understands Facebook CAPI, pixel-server deduplication logic, and the Events Manager diagnostics panel to:

• Trace why the event data drops out for Purchase and Lead calls (whether the problem sits in the server payload, hashing, or parameter mapping).
• Patch the implementation so every required field—email, phone, fbp/fbc, currency, value, etc.—is sent consistently.
• Re-test with the Facebook Test Events tool and share screenshots that show a healthy green Event Match Quality for both events.

The integration was coded directly for Facebook (no third-party wrappers), so you should be comfortable reading raw HTTP requests or Graph API calls. Please outline the steps you will follow and any logs or access you require, and let me know when you can deliver the validation proof.
