Add template-as-code sync (campaigns template NAME PATH)

Answers "can the unsubscribe template be added via git+API too": commit listmonk's own stock campaign template (already unsubscribe-capable) as email-templates/campaign.html, add a small find-or-create-or-update Template client (confirmed against knadh/listmonk's actual model/handlers), a new `template` subcommand, and a manual-dispatch-only workflow to push it in as the default campaign template. Unlike campaign sync there's no draft/live status to protect, so this is always a safe overwrite.
