nextcloud/server#59629: under PHP 8.x with OPcache,
UserConfig::getValueBool() passes a non-string from getTypedValue()
straight into strtolower(), throwing a TypeError on every authenticated
request once user_ldap is involved. Fix landed in master (PR #59646)
but no stable33 backport made it into 33.0.4.
Discover all compose-managed nextcloud containers, check whether the
`strtolower((string)` cast is already present, and `sed` it into
`lib/private/Config/UserConfig.php` on the ones that still ship the
broken version. Idempotent via grep guard so re-runs are no-ops.
Remove this block once the deployed image >= 33.0.4 ships the upstream fix.
