  - Grand total (Sold Trezorerie)
  - Casa section with total + all accounts
  - Banca section with total + all accounts
- Compact menu layout: Row 2 [Sold Companie][Trezorerie],
  Row 3 [Sold Clienti][Sold Furnizori], Row 4 [Evolutie Incasari]
- Use Romanian number format (period as thousands separator)
