Caterium v17.7.3 — Clients Server Read

- Client list and cards now consume Caterium Data Layer profiles instead of rebuilding identity only inside the UI.
- Added canonical server snapshot RPC sun_v17_clients_snapshot_v1773.
- Server profile data is preferred when available; local/legacy derivation remains the fallback.
- Order count, turnover, paid amount and order history are still calculated from the current order set and compared in Data Layer diagnostics.
- Legacy o: client rows are preserved; the snapshot canonicalizes them to p:/n: identities when possible and avoids duplicate display.
- Added workspace-scoped server client cache and refresh events.
- Existing v17.7.2 client write RPC and legacy loyalty/communication double-write remain compatible.
