864278a0fa Comprehensive audit: fix auth, basePath, security, and UI bugs 
Backend security (P0):
- Add get_current_user auth to all files endpoints (upload, decompose, url, update)
- Add get_current_user auth to all images endpoints (generate, upload, uploaded, generated, delete)
- Add get_current_user auth to slide edit and edit-html endpoints
- Add get_current_user auth to outlines SSE stream endpoint (was fully unauthenticated)

Frontend API fixes:
- adminSlice fetchTeams: bare fetch() → apiFetch() (was missing basePath prefix)
- dashboard getPresentation: add missing getHeader() auth headers
- images getUploadedImages/deleteImage: add missing getHeader() auth headers
- templates/[id] toggle layout: bare fetch() → apiFetch() (404 in production)
- header.ts: remove incorrect client-side CORS headers (Access-Control-Allow-*)

UI fixes:
- admin/users: add fetchUsers() refetch after deactivate (table wasn't updating)
- presentationGeneration.ts: fix corrupt comment with embedded import statement

Security:
- has-required-key/route.ts: remove console.log() leaking OPENAI_API_KEY to logs

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

58e738e79b Replace PPTX export pipeline: Puppeteer/python-pptx → PptxGenJS 
- New POST /api/generate-pptx route (Next.js) uses PptxGenJS to build
  PPTX directly from the Phase 8 JSON element model — no headless Chrome
- export_utils.py queries DB for slides + layout codes, POSTs payload to
  Next.js, saves binary response to disk (removes python-pptx/Puppeteer)
- Coordinate conversion: px / 96 → inches (1280×720 = 13.333×7.5 in)
- CSS color/font-size parsing (hex, rgb/rgba, px→pt at 0.75pt/px)
- Fallback renderer for slides without a JSON layout schema
- PDF export (Puppeteer) unchanged

1f5a0c27da Fix SSE proxy: create Next.js route handlers for all streaming endpoints 
Next.js rewrites() buffer HTTP responses and drop long-lived connections,
making SSE (text/event-stream) impossible. The backend never even received
the request (no log entry in API, ECONNRESET in web proxy logs).

Create dedicated route.ts files for all 3 SSE endpoints:
- /api/v1/ppt/outlines/stream/[id]
- /api/v1/ppt/presentation/stream/[id]
- /api/v1/ppt/jobs/[job_id]/stream

Each route forwards cookies for auth and returns backend's ReadableStream
directly as a Response, preventing any buffering. Sets X-Accel-Buffering: no
to also disable nginx buffering.

cf21ba4516 Phase 1-2: Foundation + Admin Panel & Client Management 
Phase 1 (Foundation):
- Project restructure (presenton-main → backend/ + frontend/)
- Database schema (8 new models, Alembic config, seed script)
- Auth (Azure AD SSO + dev bypass, JWT sessions, AuthMiddleware)
- RBAC (access_service, rbac_middleware, admin routers)
- Audit logging (fire-and-forget, AuditMiddleware, admin router)
- i18n (react-i18next with 5 namespace files)

Phase 2 (Admin Panel & Client Management):
- Admin panel shell (sidebar layout, role guard, 12 pages)
- Redux admin slice with 18 async thunks
- User management (role changes, deactivation)
- Client management (CRUD, brand config, team management)
- Brand config editor (colors, fonts, logos, voice rules)
- Master deck upload & parser (PPTX → HTML → React pipeline)
- Audit log viewer with filters and CSV/JSON export
