Generate webHtmlApp's strings, collapse a redundant string key

Strings.kt is now generated at build time (:webHtmlApp:generateStrings,
in webHtmlApp/build.gradle.kts) by parsing shared's strings.xml
directly, rather than a hand-maintained duplicate that could silently
drift from it. Names are mechanical camelCase of the XML key, so a few
call sites got more verbose (e.g. moveUp -> moveCurrencyUpContentDescription)
in exchange for zero manual sync. Only covers the base English locale.

Also collapses currency_option_label_local into currency_option_label:
the two had identical English text and existed only as a hook for a
future translation to phrase the user's own currency differently, which
no locale currently does. Removes the info.code == localeCurrencyCode
branching (and the now-pointless localeCurrencyCode parameter/field) from
all three UI implementations - PriceScreen.kt, CurrencyPickerSheet.swift,
and HtmlCurrencyPicker.kt - plus IosConverterState.localeCurrencyCode,
which existed solely to feed that branch on the Swift side.

Fixes a real regression surfaced while verifying the above by actually
building the Xcode project (not done since currencyFlagEmoji() gained
its supportsFlagEmoji parameter): Kotlin/Native doesn't generate
default-parameter overloads for Swift/ObjC-exported functions, so both
Swift call sites needed the argument passed explicitly, via the correct
exported facade name for an expect/actual pair - the actual file's
(SystemCurrencies_appleKt), not the common one (SystemCurrenciesKt).

Also drops "(DOM)" from webHtmlApp's page title.
