Added a new menu item with `permission="307"` to `_Menu.cshtml`
for accessing the `account-number-database` page. The link
is dynamically constructed using `AppSetting.Value.Domain`
and styled with `class="clik10"` and inline styles. Included
an SVG icon and the text "اطلاعات بانکی طرف حساب"
("Bank account information of the counterparty"). Maintained
the hierarchical structure of the menu.
Replaced `realPersonalContractingParty` with `legalPersonalContractingParty` to ensure correct variable usage in legal party operations. Updated the authentication logic to handle both authenticated and unauthenticated states, introducing a new `else` block for `LegalAuthentication`. Adjusted method calls (`UnAuthenticateLegalEdit` and `EditLegalPartyFromInstitution`) to use the updated variable and ensure consistent updates to legal party details.
Updated the `NationalCode` assignment in the `CreateInstitutionContractLegalPartyRequest` object to replace `"*"` with an empty string (`string.Empty`). This ensures compliance with business rules where `"*"` is not considered a valid value for `NationalCode`. Retains the original value otherwise.
