feat(grid): replace ranking/AI/score with Qlik network data

Remove ranking, AI analysis (routes + ai-copilot module), and score-engine
from the grid. Add Qlik Sense network metrics (CA, Qte, nb magasins per
product) joined by code centrale (articles.artcentrale).

- qlik-client.ts: NTLM + ticket SSO auth, QIX hypercube extraction (master items)
- qlik-network-cache.ts + qlik_network_metrics table (db-init): cache layer
- POST /api/qlik/sync?fournisseur=: per-supplier sync into cache
- SyncQlikButton: per-supplier sync, grid reload, last-update date display
- get-product-rows Phase 8: enrich rows with cached network metrics
- heatmap-grid: CA reseau / Qte reseau / Magasins (/270) / % presence columns
- discovery: app 9872ee6e, master items CA N / Quantite N / Magasin Ventes Nb N
- deps: httpntlm, ws
