fix(chat): relay unknown chat bubble ids instead of resetting to default

getBubble() fell back to NORMAL (bubble 0) for any id not in the registered
BUBBLES map, so custom client-side chat bubbles (e.g. ids 253+) rendered as
the default bubble for everyone. Now unknown positive ids (<=1000) pass
through as a transient bubble carrying that id, so the server relays it and
clients render their own .bubble-<id> style. No need to enumerate each one.
