feat: IBKR ticket in Dashboard + Journal MtM (Strike, DTE, legs)

Adds full Interactive Brokers order ticket to both the Dashboard cockpit
and the Journal de Bord MtM expanded rows. Each ticket shows the
underlying, computed strike in dollars, estimated expiry date (nearest
Friday), per-leg BUY/SELL CALL/PUT breakdown, order type LIMIT, budget
and target.

Also adds Strike and DTE columns to the MtM table and persists
strike_guidance + expiry_days_at_entry in trade_entry_prices.
