fix: extend LID resolution to message-receipt.update and contacts handlers

- message-receipt.update: resolve @lid to @s.whatsapp.net before updating
  read status, ensuring receipts match messages stored with resolved JIDs

- contacts.upsert: use lidJidAlt when contact.id contains @lid, so contacts
  are saved with the correct @s.whatsapp.net JID

- contacts.update: same LID resolution for contact updates
