fix(pdf,excalidraw): BUG-001 + BUG-002
BUG-001 (PDF stream 500) : le nom Unicode du fichier etait injecte brut
dans Content-Disposition -> en-tete HTTP invalide -> 500. Nouveau helper
_content_disposition (RFC 5987 : filename ASCII + filename*=UTF-8'').
Applique aux 2 branches /pdf/stream. Test: tests/test_pdf_stream.py.

BUG-002 (Excalidraw 'Loading...' infini) : deux causes.
1) L'import esm.sh avec ?alias=react:... etait propage a chaque dep
   transitive; esm.sh renvoie 408 sur les builds a gamme semver (jotai@>=2.9.2)
   -> import entier echoue. On retire l'alias et on utilise React 19 coherent
   (spec a gamme + target identique a celle d'Excalidraw) -> plus de 408.
2) L'editeur passait la prop legacy 'excalidrawRef', inoperante en 0.18
   (la prop reelle est 'excalidrawAPI') -> l'API n'etait jamais recue,
   le 'Loading' ne se masquait pas, save/export morts.

Verifie : 534 tests backend verts (dont 3 nouveaux PDF) + E2E navigateur
(loading masque + cycle requestSave->save OK).

# tests/test_pdf_stream.py — Regression tests for BUG-001 (PDF stream HTTP 500)
#
# BUG-001: opening a PDF whose filename contains accented characters
# (e.g. "Bière blonde envoyé par Desja.pdf") returned HTTP 500 because the raw
# Unicode name was injected into the Content-Disposition header, producing an
# invalid (non-ASCII) header value. /pdf/info worked because it sets no
# filename header.
#
# Fix: RFC 5987 header encoding (ASCII `filename` fallback + `filename*=UTF-8''…`).
import os
from pathlib import Path
# Minimal valid PDF so pypdf/stream treats the bytes as a real PDF.
