[EPIC-002] feat: Add user_id FK to employees + rename warehouse_type

Browse Source 
T2.1: Renamed warehouse_type -> construction_warehouse_type
      in almacenes_proyecto to avoid naming conflict with ERP-Core

T2.3: Added user_id column to hr.employees
      - Optional FK to auth.users (employee may not have system access)
      - Unique constraint for 1:1 mapping
      - Conditional FK (only created if auth.users exists)
