Campaign-link welcome modals: reuse existing popup-suppression keys and keep UTM handling out of the frontend

Patterns from shipping a ?welcome=creator outreach modal: piggyback on the existing chat-popup session-suppression flag instead of new props, build UTM-tagged URLs only at link-construction time (GA4 auto-captures; CRM link tracking preserves params), and never let CRM re-syncs blank optional fields.
