Fixing issue: #472

Pull Request Overview

This PR replaces instances of context.TODO() with appropriate context objects to improve context propagation and cancellation handling across the Zeno web crawler's source components. This change ensures that operations can be properly cancelled and traced through their execution context.

Key changes:

• Replace context.TODO() with component context (s.ctx) for client operations
• Use function parameter context (ctx) where available for better scope alignment
• Remove unused context import where no longer needed
