fix(coherence): Align backend types with DDL (E-COH-001, E-COH-003)
COHERENCIA FIXES P0 (ST1.1 + ST1.2 - 45min total) ST1.1 (E-COH-001 - 15min): - Fixed backend UserRole enum to match DDL - Changed: investor→user, removed student/instructor, added analyst - Deprecated requireInstructor guard (role doesn't exist in DDL) ST1.2 (E-COH-003 - 30min): - Created investment.types.ts with all enums from DDL - Centralized types: TradingAgent, RiskProfile, AccountStatus, DistributionFrequency, TransactionType, TransactionStatus - Updated all imports in repositories, services, controllers Impact: - Type safety across auth and investment modules - Coherence with DDL (source of truth) guaranteed - Eliminated type duplication and inconsistencies Modified files: - src/modules/auth/types/auth.types.ts - src/core/guards/auth.guard.ts - src/modules/investment/types/investment.types.ts (NEW) - src/modules/investment/repositories/account.repository.ts - src/modules/investment/services/account.service.ts - src/modules/investment/services/product.service.ts - src/modules/investment/controllers/investment.controller.ts Task: TASK-2026-01-26-ANALYSIS-INTEGRATION-PLAN Subtasks: ST1.1, ST1.2 Epics: OQI-001, OQI-004 Priority: P0 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
