Fix ir.model.relation field validation error and improve error handling\n\n- Add proper error handling for ValueError when querying ir.model.relation\n- Catch 'Invalid field' errors specifically and provide graceful fallback\n- Log warning messages with details about the field validation issues\n- Continue with derivation logic when relation table queries fail\n- This prevents crashes when ir.model.relation field names are incorrect\n\nThis fixes the critical Odoo server error that was preventing relation queries.
