Add exportBalanceMonitoringToExcel to FinanceApiService (server-side
blob download hitting reports/balance-monitoring?export=excel). Wire it
into BalanceMonitoringTab via a Dropdown export button in the tab
actions. Wrap the handler in useCallback to prevent an infinite
setTabActions loop caused by a new function reference on every render.

Replace single-select customerFilter/salesFilter with OptionType[] multi-select
(customers, salesPersons, filterBy), switch SWR to httpClientFetcher with explicit
type, remove PDF export, enableReinitialize, useRef modal hack, useMemo on data/meta,
and useCallback on trivial handlers. Add formikResetHandler using resetFilter().
