Phase 1 WP-1: EF Core DbContext with Fluent API mappings for all 26 entities

ScadaLinkDbContext with 10 configuration classes (Fluent API only), initial migration creating 25 tables, environment-aware migration helper (auto-apply dev, validate-only prod), DesignTimeDbContextFactory, optimistic concurrency on DeploymentRecord. 20 tests verify schema, CRUD, relationships, cascades.
