MHSanaei a061a0ca87 fix(email): bound every SMTP step with a connection deadline ...

The "starttls"/"none" transport delivered through net/smtp.SendMail, which
dials with an untimed net.Dial and never sets a socket deadline. When an
SMTP server accepted the TCP connection but then stalled (or was a
blackhole), the caller was released by Send's 30s select, but the sender
goroutine and its socket stayed blocked until the OS TCP timeout — minutes
per notification, leaking a goroutine and a connection each time.
sendWithTLS dialed with a timeout but likewise armed no deadline on the
protocol phase, and TestConnection (called synchronously from the settings
handler, with no select guard) could hang the request indefinitely.

Replace SendMail with sendPlain, which dials with smtpConnectTimeout and
arms conn.SetDeadline(smtpDeadline) before the greeting read, preserving
SendMail's opportunistic STARTTLS upgrade. Arm the same deadline in
sendWithTLS and TestConnection so every SMTP step is bounded.
