fix(search,excalidraw,e2e): recherche cassee + corruption .excalidraw.md + tests E2E #78

- frontend/js/search.js : onSearchFilter appelee avec (vault, query, results) — renvoyait undefined, cassait le rendu et basculait sur la recherche offline (0 resultat). Regression plugins depuis 30f2df3.
- frontend/excalidraw-editor.html + js/excalidraw-viewer.js : ignorer onChange au montage (plus d'auto-save spurieux qui reecrivait .excalidraw.md en JSON brut) + preservation du format Obsidian frontmatter + compressed-json a la sauvegarde.
- frontend/js/app.js : __OBSIGATE_BOOTED pose apres init() (splash + E2E attendent les handlers lies).
- tests/e2e : goHome/login attendent le boot ; excalidraw.spec.js reecrit avec les selecteurs reels (modal, context menu, canvas.first()).
- ROADMAP : C8 (creation via menu contextuel) marque fait.
- Verifie : 86/86 E2E chromium-desktop, 599 backend, ruff, validate-imports, JSDOM.
