Major feature and other changes.

[Wreck-X]

This PR introduces several key features aimed at improving the attendance management system. The updates include new GraphQL endpoints, scheduled tasks for attendance updates, enhanced security measures, and calculations for time-in and time-out.
Key Features

GraphQL Endpoints for Attendance Management:

Add Members: Implemented a new GraphQL endpoint that allows for the addition of members to the system. This provides an efficient way to manage member registrations.
Mark Attendance: Introduced an endpoint for marking attendance, facilitating real-time updates to the attendance records.

Scheduled Task for Daily Attendance Updates:

Added a scheduled task that runs at midnight to automatically update the attendance table for the new day. This ensures that attendance records are refreshed daily without manual intervention.

Enhanced Security with SHA-2 Hashing:

Implemented hashing using SHA-2 combined with a secret key to uniquely identify each ESP (Embedded Systems Platform). This enhancement improves data integrity and security, making it more difficult to spoof identities.

Time Tracking Calculations:

Developed calculations for time-in and time-out to accurately track attendance duration. This feature provides clearer insights into member attendance patterns and ensures reliable reporting.
