Fix accounting table discovery to use correct Dolibarr tables

Updated:
- Focus on accounting_line table (most likely to exist)
- Added comprehensive table discovery with column structure
- Check for accounting_account, accounting_journal, accounting_line
- Removed dependency on _bookkeeping tables
- Will discover actual table structure in your Dolibarr installation
