fix(chats): use abt xmlns and protocol 1 for fetchProps to avoid bad-request

Aligns with Baileys upstream PR #2473. Server rejects the previous
combination (xmlns=w, protocol=2, hash=''), returning bad-request and
dropping AB props on connect. Switches to xmlns=abt with protocol=1 and
omits the hash attr entirely when empty.
