_authelia_provision_oidc_client() gained a new out-param,
OIDC_AUTHELIA_PORTAL_URL, read back from the instance's own
configuration.yml (session.cookies[].authelia_url) — the actual source of
truth for where the portal lives — instead of every caller separately
assuming "https://auth.$domain".
install_authelia() and add_authelia_domain() both still default new
instances to "auth." as before (unchanged), but that's just a default, not
a guarantee: it's plain text in configuration.yml and gets hand-edited on
some boxes (e.g. a dedicated instance renamed to "authelia." to avoid
colliding with another instance's "auth." on a different machine). Mealie,
ActualBudget, and Gitea's native-OIDC wiring all independently hardcoded
"auth." when building their discovery URL, so a renamed portal silently
produced a discovery URL pointing at a host that doesn't serve Authelia —
surfacing as an opaque 500 during the OIDC token exchange with no useful
client-side error.
Verified the new awk parse against both a default ("auth.") and a renamed
("authelia.") cookies block before trusting it.
