feat(app): settings menu with language and display unit

Add global AppConfig (config.json, blueprint §8) persisting language and amount unit. CoinAmount gains unit-aware formatting and parsing (PLM, mPLM, µPLM, sat), applied everywhere amounts are shown or entered, including the send form. New Loc i18n layer (it/en) with live-updating XAML bindings covering menu, wizard, wallet panel and status messages. The Impostazioni menu opens a dropdown with separate Lingua and Unità entries (radio-checked submenus, applied and saved on click), ready to host future settings.
