fix(helm): allow empty NEXT_PUBLIC_SOCKET_URL in values schema

The default in values.yaml is now "" (empty string), which falls back to
the page origin at runtime. The schema previously required a valid URI,
which would reject the default. Mirror the INTERNAL_API_BASE_URL pattern
using anyOf with const "". Also add TRUSTED_ORIGINS to the schema.
