Add a trade history CSV export button on the portfolio page

[Chucks1093]

Summary

Investors who want to report gains or do their own analysis have no way to export their trade history. A CSV export button on the trade history tab should fetch all trades for the wallet and download them as a formatted CSV file.

Scope

• Add an Export CSV button to the trade history tab header on the portfolio page
• Fetch all trades from GET /users/:wallet/trades without pagination on export click
• Generate a CSV with columns: Date, Key Name, Type, Quantity, Price per Key, Total, Fee
• Trigger a file download with filename trades-[wallet-truncated]-[date].csv
• Show a loading spinner on the Export button while the fetch is in progress

Acceptance Criteria

• CSV downloaded with correct columns and data
• Filename includes truncated wallet and current date
• Loading spinner shown during fetch
• All trades included without pagination limit
• Button accessible only when the user is authenticated

ETA: 12 hours

Hi, I'd like to claim this issue.

I will implement the trade history CSV export on the portfolio page:

• Add an Export CSV button with a loading spinner to the trade history tab header, accessible for authenticated users.
• Fetch all wallet trades via GET /users/:wallet/trades without pagination limits upon click.
• Format and trigger the CSV file download with the required columns (Date, Key Name, Type, Quantity, Price per Key, Total, Fee) and filename scheme (trades-[wallet-truncated]-[date].csv).
• Verify data formatting, loading states, and edge cases.
