Subject: [PATCH] fix: add @lid format support and allowFrom wildcard handling

- Add support for WhatsApp Linked ID (@lid) format in jidToE164()
- Use existing lid-mapping-*_reverse.json files for LID resolution
- Fix allowFrom wildcard '*' to actually allow all senders
- Maintain backward compatibility with @s.whatsapp.net format

Fixes issues where:
- Messages from newer WhatsApp versions are silently dropped
- allowFrom: ['*'] configuration doesn't work as documented
