Add script to create promotional booklet video assets
This commit introduces a new Python script, `make_book.py`, which generates the cover and pages for a promotional booklet video. The script processes a cover photo by straightening it and applying a white overlay to a stage line, and it extracts pages from a provided PDF using the `pdftoppm` utility. The output includes a JPEG cover and individual page images, facilitating the creation of a video showcasing the booklet.

feat(main): update class progress handling to retain student history across classes
feat(index): enhance logout button styling for better accessibility and visibility
test: adjust assertions to reflect changes in class progress tracking and student data
feat(scoring): measure against فدوى too, and show every native baseline in the trace dashboard
- The native baseline now uses two TTS voices: ראאף (generated on demand) and فدوى (used when cached).
Each sound is still measured against the lowest score any voice got on it.
- References are read with wav_for_voice: wav() turned any voice outside playback into ראאף.
- Each Reference carries its voice name; the trace keeps every voice's score per sound
(baseline stage `refs`, references[].voice).
- Trace dashboard: a row per voice under each sound (the voice used in bold), a marker per
voice on the waterfall's baseline step, per-voice tooltip and table columns.
- The mock trace has two voices.
Bench on 2,828 lab recordings (all said right): false rejections 3.6% -> 2.9%
(ħ 6.0 -> 2.8%, h 9.7 -> 5.4%, ɣ 20.6 -> 12.5%, ʕ 12.5 -> 9.5%). Detection is not measured:
the lab has no recordings with a planted mistake yet.
