Add finished-roast .alog uploads with Pi agent deep review and /roasts history

- POST /api/roasts stores the original .alog verbatim (multiple per plan),
  parses it server-side, and kicks off an async zero-tool Pi agent review
  (grade, highlights, concerns, next-batch suggestions, plan-vs-actual)
- /roasts page: table of historical actual roasts with review summaries;
  row detail renders the BT curve as SVG with the plan curve overlaid,
  shows the full review, and offers original-.alog backup download,
  re-evaluate, and delete
- Planner's Reference curve drawer gains a multi-file finished-roast
  uploader that attaches to the open (synced) plan
- Failed reviews record the error on the row and are retryable via
  POST /api/roasts/:id/evaluate (e.g. once a model is configured)

+- **Finished-roast log with Pi agent review** — upload one or more finished Artisan `.alog`

+  as a backup), parsed, and deep-reviewed asynchronously by the same zero-tool Pi agent

   development, drop, and the four sanity-check ratios) recomputes as you type, using the
   exact same arithmetic as the paper worksheet (verified against both its worked examples).
