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.

SvelteKit server-side 301 redirect strips UTM params, breaking Google Analytics and affiliate attribution

Server-side 301 redirect to strip tracking query params (utm_source, utm_medium, ref, etc.) breaks Google Analytics and affiliate attribution. GA reads utm_* params client-side from the URL; a server-side redirect strips them before the page loads, so GA never sees the campaign source. Same issue…

SvelteKit SEO: Canonical tag ignores query params in Google Search Console
