[14.0][IMP] account_financial_report: general ledger account range

[WesleyOliveira98]

This improvement allows filtering accounts by range in the General Ledger for chart of accounts that use a dotted format, such as 1.1.1.01. Currently, this functionality is not available because accounts with dots fail the isdigit() check.

Brazilian Chart of Accounts Example (https://github.com/OCA/l10n-brazil/blob/14.0/l10n_br_coa_simple/data/account.account.template.csv)

General Ledger with Brazilian Accounts

When attempting to remove dots from accounts and compare them as integers using the filtered method, the filter does not apply correctly if the accounts have different numbers of digits (when we use the search method, this isn't a problem). So, we implemented a solution where we search for the position of each account in the chart of accounts, finding the position of the start_range account and the end_range account, and then retrieve the accounts between these positions.

It was necessary to search for the last appearance of the end_range code in case you have the same account code in two or more different companies, the index method returns the first appearance of the code, we also added some unit tests
