### Fixed - **Database**: Renamed default system area from "Unknown Area" to "Home" to correctly reflect default area assignment. - **Backend API**: Restored missing backend API endpoints for `/api/pppoe-packages` under the billing route group. Created the required `PPPoEPackageRepository`, `PPPoEPackageService`, and `PPPoEPackageHandler` dependencies. This fixes the HTTP 404 Not Found error previously encountered when loading the Customer Details page and attempting to add or modify a PPPoE subscription. - **Customer Manager**: Resolved infinite "memuat pelanggan" (loading) state on `/manager/customers` by adding proper null/undefined safeguards (`|| []`) for API payloads in the customer state model and `CustomerTable.svelte`. - **Financial Dashboard**: Fixed Svelte 5 strict iteration fatal crashes (`TypeError`) on `/manager/pembukuan` and `MobilePembukuan.svelte` by ensuring fallback objects and arrays exist before looping.
