fix: Analysis page now uses unified prompt executor (Issue #28)

BREAKING: Analysis page switched from old /insights/run to new /prompts/execute

Changes:
- Backend: Added save=true parameter to /prompts/execute
  - When enabled, saves final output to ai_insights table
  - Extracts content from pipeline output (last stage)
- Frontend api.js: Added save parameter to executeUnifiedPrompt()
- Frontend Analysis.jsx: Switched from api.runInsight() to api.executeUnifiedPrompt()
  - Transforms new result format to match InsightCard expectations
  - Pipeline outputs properly extracted and displayed

Fixes: PIPELINE_MASTER responses (old template being sent to AI)
The old /insights/run endpoint used raw template field, which for the
legacy "pipeline" prompt was literally "PIPELINE_MASTER". The new
executor properly handles stages and data processing.
