Enhance SIDAK with two-way KK-KTP linkage, scanner mobile optimization, NIK validation, and UI improvements

- Implement bidirectional KK-KTP linkage system (address-based & NIK-based)
- Optimize scanner for mobile devices (touch slop, larger hit areas, modal locking)
- Add NIK validation (16-digit numeric) with client-side feedback
- Set default RT/RW values to '000' for both KK and KTP forms
- Change 'Kpl Keluarga' label to 'Kepala Keluarga'
- Improve scanner error messages and user feedback
- Remove redundant 'Deteksi Dokumen' button
- Add database schema updates and Docker support files
