Using localhost as the EHLO identity is the Go net/smtp default but is
rejected by strict relays such as Google Workspace. os.Hostname() is
the conventional SMTP client fallback and returns the actual machine or
pod name in production environments.

Google Workspace SMTP relay (smtp-relay.gmail.com) rejects generic
EHLO identifiers such as "localhost", which is Go net/smtp's default.
Operators can now set SMTP_HELLO_NAME to a valid hostname so that
c.Hello() is called before StartTLS, satisfying strict relay policies.

Replace hand-rolled polling loops, semaphores, and WaitGroups
in all 7 background workers with go.gearno.de/kit/worker. Each
worker now implements Handler[T] (Claim/Process) and optionally
StaleRecoverer, gaining automatic Prometheus metrics and
OpenTelemetry tracing. Bumps kit from v0.3.0 to v0.5.0.

When an email has a sender name set (the organization name), the
mailer composes the From header as "OrgName via Probo" instead of
the default global sender name. This gives compliance page
recipients clearer context about which organization is contacting
them.
