fix: handle 'number' property in /chat/whatsappNumbers endpoint

[magodosreis]

Description
This PR fixes a type error in the /chat/whatsappNumbers endpoint. The current implementation was expecting a structure that caused failures when the number property was provided directly. It also ensures the lid property is correctly handled in the response.

Payload Comparison
Before:

JSON
[
    {
        "jid": "xxxxxxx@s.whatsapp.net",
        "exists": true
    }
]
After:

JSON
[
    {
        "jid": `"xxxxxxx@s.whatsapp.net",`
        "exists": true,
        "lid": "xxxxxx@lid"
    }
]

Changes
Adjusted the whatsappNumbers service to correctly handle the number property.

Included support for the lid (List ID) property in the response object.

Improved stability for the /chat/whatsappNumbers query.````
