### Overall Objective:
Enhance the trader-magic system by adding liquidation controls and symbol-specific trading state management to improve trading safety and usability.
### Phase Objective:
Add a Play/Pause control to each symbol’s card, enabling users to pause and resume trading for that specific symbol independently.
### Tasks for This Phase:
• Introduce a Play/Pause toggle button within each symbol’s UI card.
• Visually indicate the current trading status (active or paused) to the user clearly.
• Implement backend logic to manage the paused or active trading state per symbol, ensuring trades are only executed for symbols marked as active.
• Ensure seamless immediate pausing and resumption of trading processes when toggled.
• Implement comprehensive error handling and responsive UI feedback upon state changes.
