Initial import: shopdb-flask multi-site asset platform

Flask + Vue rewrite of the classic-ASP shopdb, built as a plugin
framework so sister GE Aerospace sites can adopt it. Product version
0.7.0-pre-0.8.0, plugin contract 0.11.0, 966 backend tests.

Key entry points:
- docs/INSTALL-WINDOWS-IIS.md - tested Windows + IIS install runbook
  (own-site and subpath deployment methods)
- docs/PILOT-DEPLOY.md - production pilot: stand up + import + verify
- docs/IMPORT-API.md - schema-agnostic legacy data import contract
- scripts/site_imports/wjf/ - West Jefferson reference import loader
- docs/adr/ - twelve accepted architecture decision records

+"""Tests for the shopfloor TV feed (/api/notifications/shopfloor).
+
+Since the notification-type display rework, per-employee fan-out is driven by
+the type's splitperemployee column (seeded true for Recognition/Training):
+a note naming several comma-joined SSOs yields one card per employee; types
+without the flag stay a single card.
