feat(DialogGuidance): Show idea detection rubric in grading tool

[Aaron-Detre]

Changes

• Added a dialog window that pops up in the bottom right of the screen when "Show detectable ideas" is clicked. This window shows the description of the AI model if one has been authored, and it displays all ideas that the AI model is looking for, along with any student-friendly descriptions that have been provided for those ideas.
• Extracted IdeaData type to its own class along with two functions for converting between IdeaData and CRaterIdea.

Test

• Clicking "Detectable ideas rubric" opens the rubric.
• Clicking the X in the corner closes the rubric.
• If a description for the AI model has been authored, it is shown above the table.
• If no description for the AI model has been authored, nothing is shown between the title and the table.
• All the ideas the CRater is trying to detect are in the table.
• Only the ideas the CRater is trying to detect are in the table (random entries in ideaDescriptions are ignored).
• Idea IDs are sorted alphanumerically.
• If no idea description has been authored for an idea, the description cell is left empty.
• Long idea descriptions wrap around to a new line.
• The link to the rubric doesn't appear during the AI chat on a dialog guidance component.

Closes #2126

Nice start. Seems to work as described.

I noticed that if you close the dialog by hitting the escape button, subsequent dialogs won't appear.

@breity can you please take a stab at styling?

Also, see my code improvement suggestions inline.

Functionality looks good. 👍

I updated the styles and added keyboard accessibility to the "Detectable ideas" links.
