Fix: Data inconsistency pada transisi tahun/bulan dan setup API lokal untuk testing

- Fix deteksi transisi bulan untuk semua bulan (tidak hanya 1 Januari)
- Perbaikan validasi data dengan threshold 20% untuk transisi bulan/tahun
- Auto-reset chart jika data hourly tidak valid
- Setup force local mode untuk testing API lokal
- Perbaikan normalisasi dan validasi tanggal
- Enhanced logging untuk debugging transisi
