Vadym Samoilenko 587f5ef6e1 Add 3 sandbox features: diagrams, mermaid, and template code-gen 
Feature 1 — PPTX from Template (Code-Gen):
- backend/services/template_codegen_service.py: analyze PPTX, strip slides,
  Gemini code-gen + subprocess exec (60s timeout, auto-retry on error)
- backend/api/v1/ppt/endpoints/template_codegen.py: POST /template-codegen/generate
  (multipart: presentation_id + template_file + custom_prompt, rate-limited 3/min)
- frontend/components/TemplateCodegenExport.tsx: drag-drop modal
- Header.tsx: "Export from Template" option in export dropdown

Feature 2 — Diagrams in Slides:
- backend/models/diagram_data.py: DiagramData / FlowStep / BarChartItem models
- generate_slide_content.py: optional __diagram__ + __mermaid__ fields in LLM schema
- DiagramRenderer.tsx: pure React flowchart / bar chart / pie chart (no deps)
- SlideRenderer.tsx: chart elements render DiagramRenderer/MermaidRenderer;
  floating overlay fallback when no chart element exists in JSON layout
- V1ContentRender.tsx: diagram/mermaid overlay on built-in template slides
- generate-pptx/route.ts: addDiagramToSlide() — bar/pie via pptxgenjs addChart(),
  flowchart via addShape()+addText(), mermaid via /api/mermaid-to-image

Feature 3 — Mermaid Diagrams:
- MermaidRenderer.tsx: dynamic import mermaid@11, useEffect render, error fallback
- frontend/app/api/mermaid-to-image/route.ts: Puppeteer renders Mermaid to PNG → base64
