Previously fixed StatCard components but missed the Debug Info section,
causing "Cannot read properties of undefined (reading 'total_pnl')" error
when account data is loading or incomplete.
Root cause:
- Frontend uses SWR with async data fetching (5s refresh interval)
- During initial load or API delays, account object may exist but fields undefined
- Previous fix (93e331a) only covered StatCard section (lines 369-384)
- Debug Info section (lines 360-362) still used direct property access
Changes:
- Add optional chaining (?.) to all account field accesses in Debug Info
- Add fallback values ('0.00') for undefined fields
- Ensures consistent null safety across all account data displays
This prevents runtime errors during data loading and API failures.
Fixes: TypeError: Cannot read properties of undefined (reading 'total_pnl')
