#89322 fixed the bridge-local normalizeWhatsAppId, but bridge.js has since
moved its id handling to bridge_helpers.js::normalizeWhatsAppId, which still
turned `<user>:<device>@lid` into the malformed `<user>@<device>@lid` for
mentionedJid / quoted participant / reaction keys, and the Python side
(gateway/platforms/whatsapp_common.py::_normalize_whatsapp_id) did the same
':'->'@' swap on botIds. Drop the local duplicate in bridge.js, import the
helper, and strip the `:<device>` suffix on both layers so the bot's own ids
compare equal to the bare ids WhatsApp sends for mentions and quotes.
One invariant test: device-qualified botIds match a bare mentionedId and a
bare quotedParticipant; a plain group message still does not trigger.
