fix(coherence): Create centralized portfolio types (E-COH-004, ST1.3)

- Created src/types/portfolio.types.ts
- Added all portfolio type definitions aligned with DDL
- Includes WebSocket event types for real-time updates
- Types match backend portfolio.types.ts structure

Part of coherence gap fix E-COH-004 - Frontend portfolio types.
Types align with DDL schema (portfolio.* enums and tables).
