Use official Resend SDK and remove sender field

Switch email sending to the official resend package and simplify the API. Removed the sender field from EmailRequest and the send_email call; send_email_resend now reads RESEND_API_KEY from the resend client, uses resend.Emails.send with a default from address ("NX <nx@goldlabel.pro>"), and returns the SDK response as a dict. Updated requirements to add resend and pydantic[email]. Error handling still returns an error dict on exceptions.
