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) Co-Authored-By: Claude Fable 5 <[email protected]>
