Separate Country Selection from Base Currency

Currently, when creating a new portfolio, the country selection automatically sets the base currency (e.g., choosing Turkey forces TRY). This is confusing for investors who live in one country but invest entirely in another currency (e.g., USD). Why It Matters: Many investors outside the US invest exclusively in USD. Users should be able to set their residence country for tax/reporting purposes while separately selecting their preferred base currency for investments. Forcing a link between country and currency creates confusion and unnecessary workarounds. Suggested Improvement: Allow users to choose residence country and base currency as independent settings during portfolio setup.
