* feat: add configurable SMTP HELO hostname
Allow the SMTP HELO/EHLO hostname to be configured separately from
the SMTP server hostname.
This is useful when the SMTP server requires clients to identify
themselves with a fully qualified hostname different from the server
address.
* chore: remove vendored dependency changes
* Bump go-pkgz/notify to v1.4.0 and document SMTP_HELO_HOST
The HELOHost field lands in go-pkgz/notify v1.4.0, so the branch needs the
bump to compile; v1.3.0 in master has no such field. The example module is
tidied alongside, as any change to backend/go.mod requires.
Documents the parameter in the parameters table and, separately, in the email
setup page: what it does, that leaving it unset keeps the previous `localhost`
greeting, and the case it exists for, a relay refusing the greeting under
Postfix `reject_non_fqdn_helo_hostname`.
Also records the current limit: verification emails for email authentication
go through go-pkgz/auth's own sender, which has no equivalent setting, so the
greeting there is unchanged.
* Bump go-pkgz/auth to v2.2.0 and apply SMTP_HELO_HOST to verification email
The verification email sender had no way to set the greeting, so a relay that
refuses the HELO would accept notifications and still reject sign-in emails.
EmailParams gains HELOHost in go-pkgz/auth v2.2.0, so the same SMTP_HELO_HOST
now drives both paths.
The example module is tidied alongside, as any change to backend/go.mod
requires.

Bumps go-pkgz/auth to v2.1.5, which adds avatar.ErrNotFound. deleteMeRequestCtrl's
avatar removal was best-effort (log and continue on any error) because before the
sentinel there was no portable way to tell an already-removed avatar from a genuine
failure. It now tolerates only errors.Is(err, avatar.ErrNotFound) - keeping the
repeated-request idempotency - and surfaces any other store failure as 500.
