Restores missing '.buildth.ing' domain segment in Vector elasticsearch endpoint for benchmark, dev, and edp instances. Template source uses {{{ .Env.DOMAIN_O12Y }}} (correct) — instances were mis-hydrated, omitting the TLD suffix.
- Fix broken remote write URL (o12y.observability./ → o12y.observability.buildth.ing/) - Create manifests/ dirs with .gitkeep for benchmark.t09.de and edp.buildth.ing - Copy forgejo-scrape.yaml VMServiceScrape manifest to both instances
