### PURPOSE
- In Guatemala, a Factura Especial (FESP) is a legal mechanism established in 
  Art. 52 of the VAT Law.
- Generate Factura Especial (FESP) when registering a purchase without a 
  supplier invoice.
- Include all required data: supplier as receiver, transaction details, and the 
  retention complement (100% VAT + ISR withholding).

  taxes withheld = recorded as liabilities to be paid to SAT.
- Fulfill FEL technical requirements (DTE XML, mandatory phrase, retention
  complement, see example attached).

### SPECIFICATION
- Added flow for FESP (Factura Especial) document type in vendor bills.
- Automatically added Phrase Type 5, Scenario 1 (as required by SAT).
- Enforced mandatory data by raising UserError if FESP is selected but
  no withholding taxes are set on the product lines.
- Added complement generation for withheld taxes (IVA, ISR) with base, rate, 
  and amounts.
- Allow users to send a document to SAT in case of FESP. 
- Added required details in FEL XML for FESP.

[ADD] l10n_pe_reports_lib: Peruvian 5th and 6th Inventory and Balance reports

PR #89744

Enterprise18.0accountl10n_pe_reports_lib

This update adds the ability to generate Peruvian 5th and 6th Inventory and Balance reports as part of the general ledger. These reports now include necessary data for Peruvian accounting standards, leveraging direct SQL queries for efficiency and covering data not typically found in standard reports.

Original PR description

Adding 'Inventory and Balance' export option to the Peruvian general ledger report, and fields required for these reports to account_account and res_company. Report lines are handled with direct SQL queries since no UI display is required for this one, and some elements needed are outside of the scope of the usual reports model.
