fix: dashboard investment display and budget health

- Exclude FixedCategories (Housing, Utilities, Subscriptions, Investments)
  from budget health panel — they are committed costs, not variable spend
- Portfolio card and stocks panel now degrade gracefully to cost basis
  when Yahoo Finance prices are unavailable, instead of showing €0
- Stocks panel shows "cost basis" label per holding when live prices
  are not available
