Fix: Save candidate transcription in process_response method

[Copilot]

Agent transcription was incomplete for Video System interviews - only interviewer questions were saved to transcription files, not candidate responses.

Changes

• Agent/src/core/interviewagent.py: Added save_transcription() call in process_response() for candidate responses
• .gitignore: Excluded node_modules and staticfiles from version control

Implementation

async def process_response(self, response):
    # ... existing code ...
    response_text = getattr(response, 'text', '')
    
    # Save candidate's response transcription
    await save_transcription(self.session_id, "candidate", response_text)
    
    # Add candidate response to internal transcript
    self.transcript["dialogue"].append({
        "speaker": "candidate",
        "text": response_text,
        "timestamp": datetime.utcnow().isoformat()
    })
    # ... rest of evaluation logic ...

This mirrors the existing pattern in ask_question() which already saves interviewer questions via save_transcription(). Both now populate data/transcription_{session_id}.json with complete Q&A pairs.
