Develop API for Task and OOO Request Management for Calendar View

[surajmaity1]

Issue Description

Create backend API to support retrieving task details and OOO (out-of-office) requests for super users. Implement functionality to allow approval and rejection of OOO requests.

Expected Behavior

• APIs should provide task and OOO request details for super users' needs.
• APIs should support approval/rejection actions for OOO requests.
• APIs should ensure secure, efficient access for super users.

Current Behavior

• No dedicated API endpoint exists to fetch task details and OOO requests in a single, structured format for calendar display.
• There is no process to approve or reject OOO requests.

Additional Information

• Data Retrieval: Provide endpoints that return task details and OOO requests for a specified date or date range, formatted for easy calendar integration.
• Approval/ Rejection Endpoint: An endpoint that allows super users to approve or reject OOO requests directly, updating the status of the request in real-time.
• Access Control: Ensure these APIs are accessible only to authenticated super users, with appropriate permissions and security checks in place.
• Performance Optimization: Structure data to minimize API calls, ideally aggregating data in a single call for efficient calendar display
