Feature: Fix INACBG Total Claim Calculation

Problem: When a user adds a new INACBG code, the total claim amount does not increase as expected. Instead, it seems to reset or absorb the new code's value into the base offset. This happens because the Base Offset calculation logic uses the current list of selected codes (which includes the new code) to calculate the offset from the original total. Formula used: Offset = OriginalTotal - Sum(CurrentCodes) If user adds code: Offset = Original - (Old + New) Final Total = Offset + (Old + New) = Original.

Solution: We must distinguish between "Original Codes" (loaded from DB) and "Current Codes" (live state). The Base Offset should strictly be: BaseOffset = OriginalTotal - Sum(OriginalCodes)

Steps:

1. Add initialLoadedCodes state to INACBG_Admin_Ruangan.tsx.
2. Populate checking initialLoadedCodes in loadBillingAktifHistory when data is loaded from DB.
3. Update useEffect calculation logic to validly calculate Base Offset using initialLoadedCodes instead of selectedInacbgCodes during initialization.
4. Ensure baseKlaimOffset is calculated only once.

Refined Logic:

• If !hasInitializedBaseRef.current:
  • Calculate Sum(InitialCodes).
  • Offset = OriginalTotal - Sum(InitialCodes).
  • Set BaseOffset.
  • Mark initialized.
• Always:
  • FinalTotal = BaseOffset + Sum(CurrentCodes).
