Refactor PacketApi status checks and fix typos

Replaced all usages of PacketApi.available with PacketApi.packetStatus for more accurate status checking. Fixed a typo in getFullQQVesion to getFullQQVersion. Updated plugin_onmessage to fetch and parse messages for a user. These changes improve reliability and consistency in API status handling.
