New "Reset" button in the currency picker's top bar (next to Done), shown only when more than the pinned default currency is selected. Tapping it asks for confirmation before removing every other selected currency, via PriceViewModel.onSelectedCurrenciesReset() — same recompute/persist pattern as onFiatCurrencyToggled. Compose uses an AlertDialog; iOS/macOS uses .alert with a destructive Reset action, matching the destructive-role toolbar button that triggers it.
