feat(create): add realisasi awal input di create page

Features:
- Add realisasiAwal field to ItemForm type
- Add NumberInput for realisasi awal (optional)
- Update table preview to show realisasi awal
- Update state to send realisasiAwal to API
- Update API create to handle realisasiAwal:
  * Create APBDesItem with totalRealisasi = realisasiAwal
  * Auto-create first RealisasiItem if realisasiAwal > 0
  * Auto-calculate selisih and persentase

UX Improvements:
- User can input initial realization during create
- Optional field with clear label and description
- Auto-calculation of percentages on backend
- Single transaction for item + first realisasi
