Subject: [PATCH 1/2] feat(analytics): proxy posthog-js capture through /ingest

Add same-origin Vercel rewrites from /ingest to the PostHog US ingest and asset hosts. Set api_host to /ingest and ui_host to the PostHog app. Add a matching Vite dev-server proxy so that local capture continues to work.
