`ProfileRoute.matches()` compared `chat_id` as an exact string, so a
WhatsApp route written as a phone number never matched the JID
(`…@s.whatsapp.net`) or LID (`…@lid`) the bridge actually delivers, and
the inbound fell through to the default profile. Allowlists and session
keys already canonicalize these via `gateway.whatsapp_identity`.
Exact compare still wins first; only whatsapp / whatsapp_cloud *user*
chats get the alias intersection fallback (applied to both `chat_id` and
`parent_chat_id`). Groups, broadcasts and every other platform stay exact.
Salvaged from #85081 (Kong); parent_chat_id fallback added on top.
