feat(qlik): extract 4 decision metrics (CA/mag, couverture, marge%, rupture%)

Adds CA par Magasin, Couverture stock Qte, Marge % and Stock Rupture %
network measures to the Qlik hypercube extraction (in-page Playwright ws
+ legacy server ws), persists them in qlik_network_metrics, joins them in
getProductRows and renders 4 new grid columns with buy-signal coloring
(low coverage / high margin = green; high rupture = rose).

- qlik-client: config IDs (env-overridable, master GUIDs of app 9872ee6e),
  NetworkMetric fields, hypercube width 4->8, page height 2500->1250
- qlik-playwright: same 4 measures in the in-page hypercube + row mapping
- schema + db-init: 4 numeric columns (ALTER ADD COLUMN IF NOT EXISTS for
  existing DBs)
- cache + grid types + enrich: plumb the new fields end to end

Note: percent measures stored as raw Qlik ratio; UI renders x100 when |v|<=1.
