fix: low audit items — email channel, debug cleanup, roadmap sync, bare except logging

L18: remove comingSoon from email notification channel (SMTP backend already exists).
L19: remove console.debug useEffect from InlineCadViewer.tsx.
L20: sync ROADMAP.md priority status sections (P1/P2/P3/P8) with status snapshot — all Done.
L22: replace 8 bare except blocks in step_processor.py with logger.debug/warning
     so geometry calculation failures are visible in logs instead of silently discarded.

 ### 2026-07-22 | Workflow-Editor | _legacy_dispatch umging cancelled/rejected Pre-Check
 `_legacy_dispatch` in `dispatch_service.py` rief `render_order_line_task.delay()` direkt auf und umging damit den Pre-Check in `dispatch_order_line_render` (der cancelled/rejected Lines überspringt). Alle Legacy-Dispatch-Pfade (auch im Graph-Fallback) liefen so durch, auch für bereits gecancelte Jobs. **Lösung:** `_legacy_dispatch` ruft jetzt `dispatch_order_line_render.delay()` auf statt `render_order_line_task.delay()` direkt.

+8 `except Exception: pass/continue` Blöcke in `step_processor.py` (Kanten-Winkelberechnung, Bounding-Box, Volumen/Flächen-Properties, Dreieckszählung, STEP-Raw-Parse) unterdrückten Fehler vollständig. Debugging von kaputten STEP-Dateien war so nahezu unmöglich. **Lösung:** Alle Blöcke auf `except Exception as _exc: logger.debug(...)` umgestellt; STEP-Raw-Parse-Fehler auf `logger.warning` da relevanter.

 ### 2026-07-22 | Architecture | CORS-Origins und Order-Prefix nicht konfigurierbar
 `main.py` hatte CORS-Origins hardcoded als Python-Liste. `orders/service.py` hatte den Ordernummer-Prefix `SA-` hardcoded. Beide Werte lassen sich jetzt per Umgebungsvariable überschreiben: `CORS_ORIGINS='["https://myapp.com"]'` und `ORDER_NUMBER_PREFIX=HM`. Default-Werte bleiben unverändert, keine Migration nötig.
