fix : added console.error logging in useTasks error handlers

[tmdeveloper007]

Summary of What Has Been Done

The useTasks.js hook had console.log calls in several error-handling code paths. All three error-reporting console.log calls have been replaced with console.error for proper production error tracking.

Changes Made

1. frontend/src/hooks/useTasks.js line 55: console.log -> console.error in the getTasks catch block.
2. frontend/src/hooks/useTasks.js lines 79-84: Both console.log calls replaced with console.error in the addTask catch block.
3. frontend/src/hooks/useTasks.js line 117: console.log -> console.error in the updateTask API call catch block.

Impact it Made

• Errors in task loading, creation, and updates are now properly surfaced in browser developer consoles and production error tracking tools.
• Follows the established console.error pattern used elsewhere in the codebase.

Closes #2030
