Update sendEmail schema and implementation to allow changing of sender name
Description
The MCP doesn't expose the from.name parameter, limiting sender customization. This creates a gap with the Mailtrap Transactional API, which supports:
{
"from": {
"email": "sender@example.com",
"name": "Sender Name"
}
}
Request
Expose the from.name parameter in the MCP to allow custom sender names for better branding, user recognition, and email deliverability.
