🔴 Integrate Cancel Pool Functionality

📌 Overview

This PR adds full support for canceling an active pool, enabling users (typically pool creators ) to halt pool participation and trigger related state updates. It ensures proper on-chain interaction, user feedback, and frontend UI synchronization.

closes #51

✅ Features Implemented

• Cancel Pool Handler:
  Added logic to invoke the smart contract method that cancels an active pool, ensuring only eligible users can perform the action.

• Action State Management:
  Introduced cancelStatus state with "pending" | "success" | "error" values to track the lifecycle of the cancellation process, ensuring UI reflects current status.

• Smart Contract Interaction:
  Connected to the contract’s cancel_pool() and integrated appropriate transaction handling (loading, confirmation, error fallback).

• UI Feedback:

  • Displayed real-time status via button states and toast notifications.

• Access Control:
  Ensured only the pool creator or authorized entity can trigger cancellation.
