feat(currency): Support all current currencies #111

Web and mobile expose different currency lists. Web supports a hardcoded subset, while mobile's dependency includes obsolete codes such as VEF. Both clients need the same complete list of current ISO 4217 currencies so onboarding and every currency picker accept the same valid codes.

Checklist

• Replace the web subset with all current ISO 4217 currencies.
• Exclude historical codes such as VEF and include their current replacement, such as VES.
• Use the same list in onboarding, wallets, transactions, transfers, budgets, holdings, and settings.
• Define a shared source or update process that keeps web and mobile aligned.

Acceptance criteria

• Every current ISO 4217 currency is selectable on web and mobile.
• Historical currency codes are not offered for new wallets or defaults.
• Existing records with historical codes remain readable.
