Admin #350 — "Global" retired in curator copy, now "All Markets"

Global implies a worldwide product and makes a market admin wonder what they are not seeing. We serve two markets. Display layer only: stored scope values and the empty market column are unchanged. **Test (Tier 1, minutes):** search the admin for "Global". It should appear nowhere a curator reads. Banner reads ALL MARKETS VIEW; the authoring picker offers All Markets (NA + Europe).
