fix(sub): use safe type assertion for xhttp mode field

Browse source 
Unsafe type assertion `xhttp["mode"].(string)` panics when mode is
nil (e.g., when xhttpSettings only contains path without mode). The
panic is caught by Gin's recovery middleware and returned as HTTP 500.

Use comma-ok pattern matching the fix already applied to gRPC's
authority field in 21d98813.

Fixes #3987
