[Marketing] Track OpenAI Ads Registrations

[rasulkireev]

Summary

Rowset can now attribute completed account registrations to OpenAI Ads without measuring visitors before they grant analytics consent. The sitewide pixel is enabled only when a deployment supplies a Pixel ID, and the conversion survives signup session rotation and navigation while consent is pending.

The implementation deliberately sends no email, user identifier, or other matching data. It also keeps self-hosted deployments disconnected by default and uses OpenAI's production-safe debug behavior.

Rollout

• Set OPENAI_ADS_PIXEL_ID=8dYXMBukBoC779PidZY6ZX in the production environment.
• Complete one controlled ad-click signup after deployment and confirm one registration_completed event in Ads Manager diagnostics.
• Unset the environment variable to disable the integration without a code rollback.

Validation

• make ci-local: lint, production asset build, migration check, Django checks, 61 frontend tests, and 1,282 backend tests passed.
• OpenAI Ads setup verification passed with the Pixel requirement enabled.
• CAPI secret exposure verification reported zero findings.
