Serialize nocache regions before storing in cache

Wrap Region objects in serialize() before putting them in the cache
store so the cache layer only sees a string. This avoids issues with
Laravel 13's serializable_classes allowlist, since Region context can
contain arbitrary objects. We control the unserialize() call ourselves
with allowed_classes => true.
