feat(qlik): drop network rupture% metric and the "Sans vente 6 mois" grid tab

Stock Rupture % N saturated at 100% for high-presence products (degenerate
at the article x network grain), so remove it end to end: config id,
NetworkMetric, hypercube (width 8->7), cache, schema, enrich and grid
column. db-init drops the column on existing DBs.

Also remove the "Sans vente 6 mois" tab from the grid page: the grid now
renders directly without the tab switcher; delete the NoSalesTab component.
(The separate Stock negatif page keeps its own sans-vente tabs.)
