[MEDIUM] HomeScreen week calculation uses undefined dueDate

[Muneerali199]

filteredAppointments references dueDate inside .map(). On initial render before fetchData(), dueDate is ''. new Date('') is Invalid Date, weekNumber becomes NaN. All appointments fail filter since NaN > 1 is false.\n\nFile: Frontend/src/Screens/HomeScreen.jsx, lines 94-96\nFix: Guard filter with if (!dueDate) return [] or use loading state
