[codex] improve BrandKit full funnel QA

[jadru]

Summary

• Reworks the BrandKit full funnel across landing/demo CTAs, template start, analytics consent/events, Intercom-inspired design tokens, generated image/icon assets, and SEO/GEO endpoints.
• Adds project creation hard limits, template-backed wizard entry, billing interval handling, checkout success tracking, feedback/notification wiring, and resilient auth/config errors.
• Adds remote QA automation, focused unit/API/component tests, Supabase notification hardening migration, and the deployment QA report.

QA

• yarn lint
• yarn test (27 files, 83 tests)
• yarn build
• yarn qa:preview "https://brand-kit.jadru.com"
• Playwright remote E2E against https://brand-kit.jadru.com: public funnel, SEO/GEO, auth login, project generation/download, Free hard limit, billing checkout interval

Notes

• Vercel Production/Preview Supabase envs were updated to the active QA Supabase project during deployment QA.
• Browser Use IAB backend was unavailable in this session, so deployed browser QA was completed with Playwright Chromium and documented in docs/reports/2026-05-07-brandkit-preview-qa.md.
