fix(coherence): Add all trading enums aligned with DDL (E-COH-002, ST1.4)

- Extended src/types/trading.types.ts with all DDL trading enums
- Added OrderType, OrderSide, OrderStatus enums
- Added PositionStatus enum (open, closed, liquidated)
- Added SignalType enum (entry_long, entry_short, exit_long, exit_short, hold)
- Added ConfidenceLevel enum (low, medium, high, very_high)
- Added Timeframe enum (1m, 5m, 15m, 30m, 1h, 4h, 1d, 1w, 1M)
- Added BotType enum (paper, live, backtest)
- Added BotStatus enum (active, paused, stopped, error)
- Deprecated old Interval type in favor of Timeframe

All types now aligned with trading.* enums from DDL schema and backend types.
Replaces hardcoded string literals with proper enum definitions.
