[Feat] Add Search and Filter Functionality for Tasks

[Akshit517]

Is your feature request related to a problem? Please describe.
Taskly currently lacks a robust search and filter feature, making it difficult for users to quickly locate specific tasks, especially as the number of tasks grows. Users may feel overwhelmed without a way to streamline their task view based on their preferences or priorities.

Describe the solution you'd like
Implement an advanced search and filter functionality that allows users to:

1. Search tasks by keywords in task titles or descriptions.
2. Filter tasks by:
   • Due date (e.g., today, this week).
   • Priority levels (e.g., high, medium, low).
