[FEATURE] Support context aware alert analysis

[songkant-aws]

Is your feature request related to a problem?
Support in-context prompting experience for other dashboard plugins like alerts. Today, we see “in-context prompting” as an action a user can take on the fly quickly and easily.

What solution would you like?
Assistant dashboard has an in-place implementation called IncontextInsight component that could wrap a child component and accepts the context passed to it. In this feature, there will be a popover window around the triggered alerts that users can choose to click 'generate' button to call llm to perform summarization based on passed context.

Do you have any additional context?
