Plans

Plan catalog — single source of truth for prices, taglines, and entitlements. The SPA (BenchSubscription.vue) fetches this on mount so admin price changes don't require a frontend redeploy.

Optional ?domain= (per-domain entitlements, EPIC omicos-admin#287): the catalog is currently identical across domains (pricing parity), so the same plan list is returned and the response is simply TAGGED with the resolved domain so the SPA knows which domain it's rendering a checkout for. Unknown domains fall back to 'omics' rather than 4xx — this is a read-only catalog, and a bogus domain shouldn't break the pricing page. Omitting the param is byte-compatible with the old response apart from the additive domain field.
