Replace hardcoded Umami website IDs in all 10 Astro landing pages with
import.meta.env.PUBLIC_UMAMI_WEBSITE_ID, following the same pattern
as the web apps.
- Add UMAMI_WEBSITE_ID_*_LANDING vars for all 10 landings in .env.development
- Add landing page configs to generate-env.mjs
- Replace hardcoded IDs with env var in 7 existing Layout.astro files
- Add Umami tracking to 3 missing landings (NutriPhi, Presi, Mukke)
- Fix Todo Landing invalid ID ("todo-landing" -> proper UUID)
- Update ANALYTICS.md with new landing page IDs
