Previously a currency the active price source had no rate for was hidden
entirely, so switching sources (e.g. to CoinGecko, which quotes far fewer
fiat currencies than Coinbase) could silently drop it from the picker and
even from the user's own selection.
Every system currency is now always offered. ConverterUiState tracks which
codes the latest fetch actually priced, and both UIs (Compose and the
native SwiftUI screen, since iOS/macOS don't render Compose UI at all) show
a "Not priced by <source>" indicator for the rest, with the amount field
emptied and disabled rather than showing a stale or meaningless value.
