Fix getAccountLabel to fetch real account names from Dolibarr chart of accounts

- Removed hardcoded fallback labels that were made up
- Now properly queries accounting_account table for real account labels
- Uses entity filtering and active account filtering
- Falls back to generic 'Compte XXXX' only if account not found
- Journal table now shows actual account names from your chart of accounts
