fix: improve exchange/model edit and usage status display

- Fixed ExchangeConfigModal to use allExchanges for editing
- Improved wallet address display layout (moved to right side)
- Added privacy toggle and copy button for addresses
- Enhanced usage status for both AI models and exchanges:
  - Shows '2/3 Running' when traders are active (green badge)
  - Shows '2 Traders' when assigned but stopped (yellow badge)
  - Shows 'Idle' when enabled but not used
  - Shows 'Configured' when not enabled
