Replaces the raw "2026-09-10 10:03:54" with each platform's own
locale-formatted, no-seconds rendering (e.g. "Sep 10, 2026, 10:03 AM"
in en-US) — mirroring how amounts are already locale-formatted
elsewhere (NumberFormat.kt). Android uses the pre-java.time
Calendar/DateFormat APIs since minSdk 24 predates java.time (API 26)
and the project has no core library desugaring configured.

Compose for Web (js/wasmJs) draws everything through Skia onto a
<canvas> rather than through the browser's own text stack, so it has
no color-emoji font to fall back to — a flag's regional-indicator
codepoints render as empty tofu boxes instead of a flag. Reproduced
via a headless-Chrome screenshot of the running dev server.
Adds a per-platform supportsFlagEmoji() (true everywhere except
js/wasmJs) that currencyFlagEmoji() now checks first, so currency
rows on web just show the plain code/name with no flag rather than a
broken glyph.

Searching "Japan" now finds JPY, "Canada" finds CAD, etc. — matching
just the currency's own display name wasn't enough, since e.g.
"Canadian Dollar" doesn't contain "Canada" as a substring.
Adds a per-platform regionDisplayName(regionCode) (java.util.Locale
on JVM/Android, NSLocale on Apple, Intl.DisplayNames on web) and
reuses CurrencyFlag.kt's currency-to-country-code derivation (now
extracted as issuingCountryCodes) to look up the country/countries
behind a currency code. "EU" is hardcoded to "European Union" since
it's not a real ISO 3166-1 code platform locale data can resolve.

Adds groupDigits(), a display-only formatter that inserts the current
locale's digit-grouping separators into an amount's integer part (e.g.
"1,000,000.5" in en-US vs "1.000.000,5" in de-DE, where the roles of ","
and "." are swapped, or hi-IN's irregular "12,34,567"). Delegates to each
platform's native locale APIs (java.text.NumberFormat/DecimalFormatSymbols,
NSNumberFormatter/NSLocale, Intl.NumberFormat with BigInt for arbitrary
precision) rather than reimplementing grouping rules, and never touches the
canonical '.'-decimal strings the rest of the app parses and stores.
Applied via a Compose VisualTransformation (BTC/Sats/fiat/manual-rate
fields, plus the read-only rate display) and, on the native SwiftUI screen,
by re-deriving the field's displayed text on every change. Also made input
parsing locale-aware: sanitizeDecimalInput now recognizes the locale's own
decimal separator (e.g. what a locale-aware decimal keypad sends), not just
"." — with a stricter rule on the SwiftUI side specifically, since its
single text buffer re-feeds the grouped display back through sanitize, so
a "." can be grouping noise there rather than a decimal point.
The exceeds-max-supply warning's "21,000,000 BTC" is no longer baked into
the localized string with hardcoded grouping; it's substituted in at
runtime via groupDigits so the link-detection text always matches exactly,
in every locale.

Currency.getAvailableCurrencies() (JVM/Android) and NSLocale.ISOCurrencyCodes
(iOS/macOS) return every ISO 4217 code the platform has ever known about —
withdrawn currencies like the Deutsche Mark and French Franc, and test/
placeholder codes (XTS, XXX), included. Measured on the JVM: 232 total
codes, only 156 still assigned to a country.
Filters the list down to currencies actually assigned to an ISO country
today, which drops the withdrawn ones without needing a maintained
exclusion list. Precious metals (XAU, XAG, XPD, XPT) are added back in
since they're still actively traded despite not being tied to any country.
Web is left unfiltered — there's no reliable country-to-currency API there.

Adds a SQLDelight-backed AppDatabase (Android, Desktop, iOS/macOS) so the
converter survives restarts: the last-known rates per price source, the
user's selected fiat currencies (with order preserved), and the last-used
price source all reload before the first network fetch completes. Web isn't
a shipped platform and SQLDelight's driver there needs a worker plus a wasm
sqlite binary, so it gets a lighter localStorage-backed implementation of
the same store interfaces instead.
Android needs an app Context for its driver, wired via a new
SatsPriceApplication. iOS/macOS need libsqlite3 linked explicitly (Swift's
autolinking only covers Shared.framework itself, not its C library
dependencies), plus two extension-loading symbols marked optional since
macOS's system sqlite build omits them.
