feat: Implement admin dashboard and page collection

This commit introduces a new admin dashboard and a page collection feature. The admin dashboard allows for managing KTP data, including viewing details and exporting data. The page collection provides a structure for organizing different pages within the application.

The following files were added:

- `dashboard-admin-ktp/index.html`: HTML structure for the admin dashboard.
- `dashboard-admin-ktp/script.js`: JavaScript logic for the admin dashboard.
- `dashboard-admin-ktp/style.css`: Styling for the admin dashboard.
- `page-collection/index.html`: HTML structure for a sample page collection.
- `page-collection/script.js`: JavaScript logic for the sample page collection.
- `page-collection/style.css`: Styling for the sample page collection.
- `design-styles.json`: JSON file to store design styles.
