Remove step 2d (whatsapp-resolve-lids.ts) which pre-created duplicate
messaging_groups rows keyed by @lid alongside the phone-keyed rows.
This caused split sessions — the same contact got separate sessions
depending on which JID format arrived.
With the Baileys v7 upgrade (PR #2259 on channels), the adapter
resolves every LID to a phone JID via extractAddressingContext before
the message reaches the router, making dual rows unnecessary.
