add full quiz histrory with show more/show less functionality

[Vrushti07]

Addressed Issues:

Fixes #641

Improves the quiz dashboard history to display all generated quizzes instead of only last 5 and adds a show more/show less option to view full history.

How It Solves the Issue:

• Replaced the limited storage approach with allQuizzes to persist all generated quizzes in localStorage.
• Added a "Show More / Show Less" toggle in the Quiz Dashboard:
• Displays only the latest 5 quizzes initially for a clean UI
• Allows users to expand and view the complete quiz history when needed

This ensures no quiz data is lost while maintaining a user-friendly interface.

After :

Summary by CodeRabbit

• New Features
  • Quiz history now stores and displays all previous quizzes instead of limiting to the last 5.
  • Added "Show More" and "Show Less" buttons to toggle between the first 5 items and the complete history (Show More appears only when >5).
  • Quiz history persists across sessions for better tracking of past work.
  • Clear action removes the entire quiz history and resets the view.

Poem

🐇 I hopped through storage, a trail of quizzes bright,

Prepending each memory by soft moonlight,
Five at a time or the whole meadow's view,
Show More to wander, Show Less to renew,
A rabbit's small cheer for history made true.

In `@eduaid_web/src/pages/Previous.jsx`:
- Around line 27-30: The handleClearQuizzes function currently removes
"allQuizzes" and clears setQuizzes but doesn't reset the showAll toggle; update
handleClearQuizzes to also call setShowAll(false) so the Show More/Show Less UI
is reset when quizzes are cleared (refer to handleClearQuizzes and the
showAll/setShowAll state variables).
