Add a new notification service that sends transactional emails through the Mailtrap Email Sending API. The service uses only the Go standard library (net/http), so it introduces no new dependencies. It follows the conventions of the existing email services (sendgrid, mailgun): a New constructor, AddReceivers, a BodyFormat toggle (HTML by default, PlainText opt-out) and a Send method. Functional options cover the sender display name, bulk and sandbox hosts, a custom host, and a custom HTTP client. Includes table-driven unit tests (httptest-based) and a service README.

Description
This PR adds a new notification service for Mailtrap, an email delivery platform for developers.
The service sends transactional emails through the Mailtrap Email API.
Motivation and Context
Mailtrap is a widely used email delivery/testing platform, but notify had no Mailtrap service — users had to fall back to the generic SMTP
mailservice. This adds first-class support alongside the other email providers (sendgrid,mailgun). It uses only the Go standard library (
net/http), so it introduces no new dependencies.How Has This Been Tested?
Table-driven unit tests (
service/mailtrap/mailtrap_test.go) usinghttptest.Serverto assert the request method, path,Api-Token/Content-Typeheaders, and JSON body for both HTML and plain-text sends, plus constructor/options/error-status cases (93% coverage). Verified locally withmake ci(golangci-lint clean, fullgo test -race ./...passing) andmake fmt.I've also tested both the Sandbox and live versions by sending them to myself.
