[DO NOT MERGE][Experimental] ui changes for pipeline summarization using genai

[GnsP]

UI updates to support GenAI pipeline summary

Description

Support GenAI summarization for pipelines (both deployed and drafts / edits). This is experimental and not production ready yet.

The following aspects are missing in this PR:

1. Error handling for the summarization APIs. Currently we just keep the panel in loading state if the API fails.
2. Summarization for different versions of the same pipeline.
3. Feature flags from the backend. Currently we default to true for the feature flag added in the UI code.
