- Introduce `CalendarSystem` to abstract Gregorian and Persian date calculations for recurrences, billing cycles, and cutoffs - Replace `DateTimeFormatter` and `SimpleDateFormat` with ICU-backed `formatLocalized` utilities across all UI components and widgets - Migrate heatmap and calendar grouping logic from `YearMonth` to `LocalDate` to support non-Gregorian month lengths and boundaries - Add Farsi (`fa`) locale configuration and settings options - Implement `PersianDateCaption` to display Jalali dates alongside standard Material 3 `DatePicker` dialogs - Update notification schedulers and recurring expense calculators to respect the active calendar system - Add comprehensive unit and Paparazzi screenshot tests validating Persian calendar behaviors and localized formatting
…complete Persian translations

- Line 176: Add the missing JalaliDateRangePicker import to make the composable
used in FinishDateSelector resolve; leave the existing source-set configuration
unchanged.
- Around line 84-99: Update the usePersianPicker check in FinishDateSelector to
use CalendarSystem.current() instead of resolving the app configuration locale,
keeping the picker calendar consistent with the rest of the app.

CalendarSystem.current()from the application locale.
AppCompatDelegate.setApplicationLocales()stores the selected Farsi locale, butCalendarSystem.current()reads onlyLocale.getDefault(). With an English system locale, it returnsGREGORIANfor a Farsi app. This affects onboarding and the date calculations used for recurring charges, subscriptions, heatmaps, notifications, and budget operations.Use the active AppCompat locale in this shared resolver. The onboarding caller already uses
current(), so changing that caller alone does not fix the resolver-level mismatch.Suggested fix
+import androidx.appcompat.app.AppCompatDelegate import java.time.LocalDate import java.util.Locale @@ - fun current(): CalendarSystem = of(Locale.getDefault()) + fun current(): CalendarSystem { + val appLocale = AppCompatDelegate.getApplicationLocales().get(0) + return of(appLocale ?: Locale.getDefault()) + }🤖 Prompt for AI Agents
