Subject: [PATCH] Move MailKit and Newtonsoft.Json to patched versions

MailKit 2.10.1 is affected by GHSA-9j88-vvj5-vhgr (fixed in 4.16.0) and
Newtonsoft.Json 12.0.3 by GHSA-5crp-9r3c-p9vr (fixed in 13.0.1). With the
.NET 10 SDK, NuGet audit reports both and the solution fails to build. The
MailKit sender now references MailKit 4.18.2 and the Mailgun sender
Newtonsoft.Json 13.0.4. MailKitSender compiles against MailKit 4 unchanged.

Building against MailKit 4 also binds SendAsync to its current signature,
which fixes the MissingMethodException apps on MailKit 3 or later hit.

Fixes #296
