Added toggle for filtering failed tasks

[Tanish-Ranjan]

This commit introduces a toggle action to filter out successful tasks from the execution page and expand all failed tasks.

Fixes #970

Context

Previously, there was only the option to expand and collapse all tasks, making it harder to focus on failures. This change introduces a toggle action that, when enabled, hides successful tasks from the hierarchy in the execution page. When disabled, the full task hierarchy is restored.

This improvement makes it easier for users to debug failures without unnecessary distractions.
