Confirmed live: install_mealie() pre-computes BASE_URL as
recipes<suffix>.$SITE_DOMAIN before ever asking about Caddy, then
configure_caddy_for_service() separately prompts for a domain — which the
user can freely override (e.g. typing mealie.mydomain.com instead of
accepting the recipes.mydomain.com default). Nothing fed that choice back
into BASE_URL, so it stayed stale. Since BASE_URL is exactly what
_mealie_offer_authelia_oidc() registers as the OIDC redirect URI, this
produced Authelia's "redirect_uri does not match any of the OAuth 2.0
Client's pre-registered redirect_uris" — Caddy and DNS were both correctly
pointed at the new domain, but the client Authelia had on file still said
the old one.
Added CADDY_SERVICE_DOMAIN as a new configure_caddy_for_service() out-param
(lib/common.sh) — the same out-param convention as the existing
CADDY_SERVICE_CONFIGURED/CADDY_SERVICE_MODE, set right after the domain
prompt is accepted. install_mealie() now reconciles BASE_URL against it
immediately after the Caddy call, before the Authelia OIDC step reads
BASE_URL back out of .env. ActualBudget's equivalent OIDC offer asks for
its own domain fresh each time rather than reading a pre-computed BASE_URL,
so it isn't affected by this class of bug and needs no equivalent fix.
Verified the reconciliation logic in isolation against a synthetic .env.
