Code Testing Integration

[DavidMiserak]

User Story:
As a developer learning programming concepts,
I need to be able to test code snippets directly from flashcards
So that I can verify my understanding through execution.

Details and Assumptions:

• Support running code snippets in common languages
• Display execution results
• Handle basic input/output for testing
• Implement sandboxing for security

Acceptance Criteria:

Given a card contains an executable code snippet
When I click "Run Code"
Then the code should execute and display the results

Given a code snippet requires input
When I run the code
Then I should be prompted for input values

Given a code snippet execution results in an error
When I run the code
Then I should see a clear error message explaining the issue
