Add Workflow Information Panel in the UI

[darielnoel]

Description:
A feature to add an informational panel in the workflow interface to help users understand:

• The purpose of the workflow.
• Its input parameters.
• Expected outputs.

Is your feature request related to a problem?
Users currently lack a simple way to understand what a workflow does or what is required to execute it. This leads to confusion and a steeper learning curve.

Proposed Solution:
Add a "Workflow Information Panel" to the KaibanJS UI. This can be:

1. A hoverable info icon providing a quick summary.
2. An expandable/collapsible section displaying detailed descriptions, parameter explanations, and output expectations.

Alternatives Considered:

• Linking to external documentation for each workflow, but this adds friction.
• Embedding detailed descriptions directly in YAML/JSON files, which is not user-friendly for non-technical users.

Additional Context:
This feature will make workflows more intuitive and accessible, improving user onboarding and reducing reliance on external documentation.
