Refactored mail-related roles to support running Infinito.Nexus on nodes without a dedicated mail server: - Introduced sys-svc-mail as central mail orchestration role. - Split msmtp handling into sys-svc-mail-msmtp. - Added sys-svc-mail-smtp to provide a localhost-only Postfix relay when Mailu is not present. - Updated alert/health roles to use the new mail orchestration. - Avoid installing postfix inside containers via IS_CONTAINER guard. - Adjusted WordPress role to use the new msmtp template path. This allows lightweight deployments (e.g. Raspberry Pi, robots, edge nodes) to send mail via localhost without requiring a full Mailu stack.
