Ramkumar Chinchani bfc59ad120 security: suppress Allow-Credentials on wildcard CORS origin (CORS-1) (#3980)
fix(security): suppress Allow-Credentials on wildcard CORS origin (CORS-1)

Per CORS spec §3.2, Access-Control-Allow-Credentials must not be
"true" when Access-Control-Allow-Origin is the wildcard "*".

ACHeadersMiddleware (pkg/common/http_server.go) and
getUIHeadersHandler (pkg/api/routes.go) now only emit the
credentials header when an explicit, non-empty AllowOrigin is
configured.  Deployments that leave AllowOrigin blank (default
wildcard) no longer produce a contradictory header pair.
