afterFiles ordering was insufficient in Next.js 14 — the catch-all
/api/v1/* rewrite still intercepted SSE requests before route handlers.
Fix: add a `missing` condition on `Accept: text/event-stream` to the
rewrite rule. EventSource always sends this header, so SSE requests now
skip the rewrite entirely and are handled by the existing route handlers
(app/api/v1/ppt/outlines/stream, presentation/stream, jobs/stream).
Normal JSON API requests are unaffected.

The flat-array form of rewrites() runs as beforeFiles, intercepting /api/v1/*
requests before Next.js can match route handlers. This caused the SSE stream
endpoints (outlines/stream, presentation/stream, jobs/stream) to be handled
by the buffering HTTP proxy instead of the custom streaming route handlers,
resulting in ECONNRESET → 500 on the browser.
afterFiles rewrites only apply when no matching app/api/ file exists, so
route handlers now win over the backend proxy for all /api/v1/* paths that
have explicit handlers.

- 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

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.

- outlines.py: Fix ECONNRESET/socket-hang-up — Depends session closes before
StreamingResponse generator runs; capture presentation data upfront, use
async_session_maker() inside inner() for the final DB commit (same pattern as Phase 4)
- useCustomTemplates.ts: Filter null-template items in summary map (crashed on
presentations without a TemplateModel); use item.layout_count instead of hardcoded 0
- TemplateSelection.tsx: Move custom AI templates section above built-in templates
- presentationGeneration.ts + OutlinePage.tsx: Add selectedTemplateId to Redux so
template selection persists when navigating away and back to /outline; clearOutlines
also resets selectedTemplateId for new presentation flows
- DocumentPreviewPage.tsx: Detect JSON file content (table decomposition output) and
convert to markdown table or pretty-printed code block before passing to MarkdownRenderer

- documents_loader: skip missing files (print warning + continue) instead
of raising HTTPException inside SSE generator — prevents "response
already started" runtime error when temp files are wiped on restart
- V1ContentRender: wrap non-edit mode render in SlideErrorBoundary so
broken custom layout components show a red placeholder instead of
crashing the page (React error #62)
- CustomTemplateCard: wrap LayoutPreview in SlideErrorBoundary for the
same reason — bad compiled TSX from master deck parsing no longer
crashes the outline template picker

In layouts mode, screenshots were matched by array index (0,1,2...)
which broke when PPTX had more slideLayouts than actual slides.
Now builds an explicit mapping from slideLayout filename to the
first slide that uses it, so each layout gets the correct screenshot.
