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.

+<!--
+Listmonk's own stock campaign template (static/email-templates/default.tpl
+in knadh/listmonk), committed here verbatim as a known-good, unsubscribe-
+capable starting point rather than something invented from scratch. Synced
+into listmonk via `campaigns template <name> email-templates/campaign.html`
+(see internal/campaign/template.go) as the is_default campaign template, so
+every campaign this tool creates gets a real unsubscribe link/footer without
+per-campaign template_id wiring. Restyle freely — the two load-bearing tags
+are `{{ template "content" . }}` (where the campaign body gets injected) and
+`{{ UnsubscribeURL }}` (the actual unsubscribe link); everything else here is
+just Listmonk's default look.
