Add Solana Exam Modules to Murphy

[SaitamaCoderVN]

🧩 Context

Murphy currently provides learning modules, practice challenges, and interactive docs—but lacks formal exam-like assessments aligned to the user’s learning progression. We want to introduce structured exam modules mirroring certification quizzes and interview prep questions to help learners evaluate their mastery and feel confident in their Solana skills.

🎯 Goal

Build adaptive exam modules tied to each learning stage (Beginner, Intermediate, Advanced, Expert), providing multiple-choice questions, scenario-based challenges, and interactive feedback—helping users gauge knowledge and readiness to level up.

📌 Scope & Features
1. Curate Exam Content
• Use common Solana interview & assessment questions (e.g. from 101 Blockchains top 20 questions  , FinalRoundAI 25 Solana dev interview Qs 
• Include quiz-style content from platforms like Brainscape flashcards 
• Map questions to learning tiers (e.g. Proof of History, SPL Tokens, Anchor, PDAs, security)
2. Exam Module Architecture
• Group questions into themed exam sets per tier
• Support multiple choice + scenario-based Q&A
• Provide instant feedback & brief explanations for answers
3. Adaptive Assessment Flow
• Unlock exams after completing relevant learning modules or practice exercises
• Require passing score (e.g., ≥ 80%) to proceed to next tier
4. Interactive UI Integration
• Embed quiz interface within Murphy platform

5. Analytics & Reporting
