Subject: [PATCH] fix(whatsapp): pass authDir to jidToE164 for LID mention
 detection

WhatsApp group mentions using the new Linked ID format (@lid) were not
being detected because jidToE164() was called without the authDir needed
to find the LID reverse mapping files.

Now isBotMentioned() and debugMention() accept an optional authDir
parameter, which is passed through from account.authDir.
