Admin Module Development

You are tasked with developing an Admin Management module for a web application that includes registration, login, and a dashboard interface with navigation.

Requirements:

1. **Admin Registration Page:**
- Design a user interface for the Admin Registration page.
- Implement a "Create Admin Account" button with backend functionality.
- When an admin account is created, automatically assign the role "Admin".
- Store the new admin's credentials and role in a database table securely.
- After successful account creation, redirect the user to the Admin Login page.

2. **Admin Login Page:**
- Provide a login form for admins to enter credentials.
- Implement login functionality that authenticates credentials against the stored admin data.
- On successful login, navigate the user to the Admin Dashboard page.

3. **Admin Dashboard Page:**
- Design an Admin Dashboard page with a sidebar menu.
- The sidebar should include the following menu items:
  1. Dashboard
  2. Grounds Management
  3. Booking Management
  4. Customer Management
  5. User Authentication and Role Management
  6. Pricing and Payment Management
  7. Reporting and Analytics
  8. Maintenance and Facility Management
  9. Notifications and Alerts
 10. System Configuration
 11. Settings

Ensure all navigations between pages occur smoothly, and backend database interactions are robust and secure.

# Steps

1. Create the Admin Registration UI with a "Create Admin Account" button.
2. Implement database logic to save admin credentials with role "Admin" upon registration.
3. Redirect to the Admin Login page after successful registration.
4. Create the Admin Login UI.
5. Authenticate login credentials from the database.
6. Upon successful login, navigate to the Admin Dashboard.
7. Implement the Admin Dashboard with the sidebar containing the specified menu items.

# Output Format

- Provide complete and concise code snippets or modules for:
  - Admin Registration page (frontend and backend)
  - Admin Login page (frontend and backend)
  - Admin Dashboard page with sidebar navigation
- Include database schema or table definition relevant to admin user storage.
- Ensure code includes comments explaining key logic and navigation flow.

# Notes

- The role "Admin" must be hard-coded in account creation logic and stored in the database.
- Authentication should securely check hashed passwords if applicable.
- The UI design should be clear but does not need to be styled beyond basic usability.

This detailed specification will ensure creation of a functional Admin module with registration, login, and a dashboard with navigation as listed.
