Fix SMTP From-address fallback rejection; catalog card icon order; doc corrections

Mail sending fell back to a hardcoded noreply@theta42.com From address when
smtp.from wasn't set, which authenticated relays reject with "Sender is not
same as SMTP authenticate username" since no relay authorized this account
to send as that address. Falls back to smtp.user first now.

Also: catalog card titles now read name-then-icon instead of icon-then-name,
and a handful of docs corrections found in an accuracy pass (configuration.md
missing the OpenBao/live-config layer, plugins.md undercounting plugin types,
vault.md describing OpenBao dev-mode/root-token access that doesn't reflect
the real production setup, orphaned discovery.md/vault.md pages linked in,
README's required-groups list missing app_sso_directory_admin).
