feat: replace Astro + Sanity + Fastify with Next.js + Payload CMS

Single Next.js 15 app now serves frontend SSR, admin CMS, and Stripe API. Replaces the Sanity quota-limited headless CMS with self-hosted Payload 3.0 on Postgres, removing the split-service topology (ssr/api/proxy → web). - nextjs/: Next.js 15 app with Payload 3.0, Postgres adapter, Stripe plugin - k8s/: new single-pod deployment + Postgres StatefulSet + PVCs (media, db) - .gitea/workflows/deploy.yml: single-image build, tears down legacy pods New Gitea secrets required: PAYLOAD_SECRET, POSTGRES_PASSWORD.
