Replace AddDbContext with AddDbContextFactory for Blazor Server circuit
safety — each service method now creates a short-lived DbContext via the
factory. Configure Windows Service hosting with ContentRootPath and
remove HSTS/HTTPS redirect for reverse-proxy deployment.

Replace the single CatalogMaterialDto + CatalogDimensionsDto (bag of nullable
fields) with per-shape DTOs that have strongly-typed dimension properties.
Catalog JSON now groups materials by shape key instead of a flat array.
Delete the old SeedController/SeedDataDtos (superseded by CatalogService).
Scraper updated to emit the new grouped format, resume by default, and
save items incrementally.

Replace the standalone ExportData console app and hardcoded SeedController
with generic GET /api/catalog/export and POST /api/catalog/import endpoints.
Import uses upsert semantics with per-item error handling, preserving
existing inventory quantities.
