Subject: [PATCH 1/3] feat: add separate unpaid and paid bill totals to
 location cards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Display both unpaid and paid bill amounts in LocationCard and MonthCard
- Rename variables for clarity: totalUnpaid, totalPayed, unpaidTotal, payedTotal
- ViewLocationCard uses totalAmount for tenant bills (regardless of payment status)
- Update Croatian translations: "Ukupno neplaćeno" (unpaid), "Ukupno plaćeno" (paid)
- Add ShoppingCartIcon for unpaid amounts, BanknotesIcon for paid amounts
- Update HomePage to calculate and pass both totals to month cards

Subject: [PATCH 3/3] refactor: optimize state initialization with lazy
 initializers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Move billStates calculation into useState lazy initializer to prevent recalculation on re-renders
- Initialize allPaidMode based on billStates to reflect actual data state
- Use lazy initialization pattern for better performance
- Remove intermediate variables to simplify code
