feat(dashboard): show unrealized PnL on position cards (5min update)

Parse position monitor logs (5min interval) to update current_price,
unrealized_pnl and unrealized_pnl_pct in bot_status. Position cards
now display USDT amount and percentage, colored green/red. Falls back
to entry/current price calculation if monitor data unavailable.
