v0.20.9 – Ukrainian Translation & Shopping Category i18n

Added

• Ukrainian (uk) locale — full 622-key translation contributed by @baragoon
• Ukrainian Hryvnia (UAH) currency option in budget settings
• Shopping list category names are now translated in the settings panel; rename and delete dialogs also show the translated name

Fixed

• Server-side VALID_CURRENCIES now matches the frontend — AED, BRL, INR, and SAR were shown in the UI but rejected by the API
