services.yaml now references key: "{{HOMEPAGE_VAR_HASS_TOKEN}}" instead of
the inline long-lived HA JWT (which was exposed in this public-fronted repo
and has been rotated + revoked). Secret now lives only in observability/.env
(untracked, mode 600). Add .gitignore for .env/secrets so this can't recur.
