Serilog.Settings.Configuration cannot deserialize NetworkCredential or
MailKit's SecureSocketOptions from JSON, causing an InvalidOperationException
in the binder and preventing containers from starting.
Fix: remove Email from the WriteTo JSON array entirely and wire it in code
inside ConfigureJsonSerilog using a dedicated SerilogEmail:* config section.
The sink is skipped when From/To/Host are absent, so local dev is unaffected.
Also renames the docker-compose env vars from the verbose
Serilog__WriteTo__2__Args__* prefix to the clean SerilogEmail__* prefix.
