The previous commit added OIDC_AUTHELIA_PORTAL_URL parsing but only
tr -d '\r'-sanitized the awk output, not the input. That's insufficient
for a CRLF-tainted file (confirmed live: a configuration.yml line
hand-edited by something that saves Windows line endings) — every
line-anchored awk pattern here fails to match at all against a line like
" cookies:\r", since $ anchors end-of-string and the \r is still part of
it, not just leaves a stray \r in the captured value. Symptom was Mealie's
generated OIDC_CONFIGURATION_URL line getting split mid-string, which
Docker Compose's env parser (bare \r treated as a line break too) reported
as "unexpected character '/' in variable name".
Fixed by piping the file through tr -d '\r' before awk sees it, for both
the domain and portal-URL parses. Verified against a synthetic CRLF config
that reproduces the exact failure — both fields now parse clean.
