fix: replace wildcard CORS default with explicit localhost origins

The cors_origins setting defaulted to ["*"], which passed through
unchanged in production (non-debug) mode. Now defaults to explicit
localhost origins, and _get_cors_origins() strips any wildcards in
production with a warning.

Fixes #462
