Update the UI for displaying summaries.

This page should display the keywords and summaries. It should also display the extracted text at the top. Maybe add some relevant plots at the bottom.

To be more descriptive:

• Display the extracted text in a card that can be toggled open/close. Have it closed initially.
• Display the summaries along with the corresponding keyword in cards stacked vertically. Make each summary toggled close by default, so only the keyword is displayed. This will help when there's a lot of extracted keywords.
