Finalize Submit Ratings Flow

[emilyliublair]

Summary

Resolves #436

Checklist

• Only allow the submit course ratings flow and the button to display if a user is logged in and not on mobile mode.
• Add the ability so that if you start rating something and exit it, it prepopulates the ratings and the classes from the last time we tried to rate using local storage
• If a user has already submitted ratings for a term, don't display the Rate my courses button for that term
• Add term handling
• Add back button, exit button, and keep page on same window
• Update useSubmitRatings hook to be compatible with existing endpoints
• Invalidate cached ratings after successful submission
• Add rate limiting to prevent multiple submissions from rapid repeated clicks
• Add light mode designs

How to Test

1. Rate my courses & rate banner not displayed when user not signed in or mobile:

2. Click 'Rate my courses', rate courses without submitting, exit, and re-enter to see ratings/progress saved.
3. Submit ratings and see 'Rate my courses' button disappear. Also verify that information is updated in the Course Details page (course and professor ratings cache invalidated).
4. Click the 'Rate you Spring 2026 courses' Banner and verify that course and professor information displayed are for Spring 2026.
5. Light mode designs:

7. User cannot proceed if all fields not filled out: 8. To test rate limiting, you can modify `{type === 'signedIn' && !hasSubmitted && (` in ScheduleContainer to be `{type === 'signedIn' && (` so that the Rate my Courses button stays visible after submitting. Also, comment out: ``` useEffect(() => { const stateToSave: PersistedRatingsState = { selectedCrns: selectedSections.map((s) => s.crn), currentIndex, ratingsMap, term: ratingTerm, }; localStorage.setItem( RATINGS_STORAGE_KEY(ratingTerm), JSON.stringify(stateToSave) ); }, [selectedSections, currentIndex, ratingsMap, ratingTerm]); ``` in RatingsPage to prevent saving state. Finally, change `const RATINGS_LIMITER_INTERVAL_SEC = 5;` to `const RATINGS_LIMITER_INTERVAL_SEC = 60;` and make 2 submissions within one minute. Verify on backend/console that second submission does not go through.
