fix(financial-statements): use stored date format settings in all reports

- Replace hardcoded date formats ('YYYY/MM/DD') in all Meta classes with meta.dateFormat
- Add IFinancialReportMeta interface with baseCurrency and dateFormat fields
- Add DEFAULT_REPORT_META constant with default date format 'YYYY MMM DD'
- Update all sheet classes to accept IFinancialReportMeta parameter
- Update all services to pass dateFormat from meta to sheet constructors
- Fix customer/vendor transactions date formatting in table rows
- Add TenancyModule to SalesTaxLiabilityModule for dependency injection
- Make dateFormat optional in JournalSheet and GeneralLedger query types
