Benjamin Admin 306886a42b Phase 8: CSV + ICS export, print view, MkDocs docs, SBOM + dev-mode auth

Auth (Test-Mode):
  - middleware.AuthMiddleware now takes a devMode flag. In dev,
    requests without Authorization fall back to a deterministic dev
    UUID (00000000-...-001) and role=teacher. ENVIRONMENT=production
    re-enables the strict 401 path.
  - main.go wires devMode = cfg.Environment != "production".
  - page.tsx replaces the red 'Anmeldung noch nicht integriert' banner
    with a softer Testumgebung notice; the manual-token form moves
    behind a nested details block.

Export endpoints (school-service):
  - LoadExportLessons joins tt_lesson with tt_period for wall-clock
    times; one query feeds both CSV and ICS.
  - WriteCSV streams 10 columns including pinned flag.
  - WriteICS emits one VEVENT per lesson anchored to a Monday — caller
    overridable via ?start=YYYY-MM-DD. RFC 5545 escapes for ',', ';',
    '\n' in icsEscape().
  - NextMonday helper for the default anchor.
  - GET /timetable/solutions/:id/export.{csv,ics} handlers attach
    Content-Disposition: attachment so browsers download instead of
    rendering.

Frontend:
  - lib/stundenplan/api.ts downloadSolutionExport() fetches as blob,
    triggers a synthetic <a download> click, and forwards the JWT when
    present.
  - PlanView gains CSV / ICS / Drucken buttons next to the perspective
    selector. The toolbar carries class 'no-print' so window.print()
    yields only the grid.
  - globals.css @media print rule hides chrome, forces white
    background, gives the table proper borders for A4.

Docs:
  - docs-src/services/stundenplan/{index,architecture,constraints,
    solver-tuning,export}.md with nav entry in mkdocs.yml under
    Services → Stundenplaner.
  - sbom/stundenplan/README.md lists manually-verified key dependencies
    and the policy reference. scripts/stundenplan-sbom.sh generates
    full machine-readable inventories via go-licenses + pip-licenses
    + license-checker when those tools are available.

Tests:
  - internal/services/timetable_exports_test.go: 4 unit tests covering
    CSV column layout + quoting, ICS structure + DTSTART formatting,
    icsEscape special chars, NextMonday weekday math.
  - studio-v2/e2e/stundenplan-export.spec.ts split out of the main spec
    file (LOC budget) — 3 tests for button render, CSV download,
    ICS download.
  - mockSchoolApi extended with export.csv + export.ics routes.

Stundenplaner

Schulweiter Stundenplan-Generator fuer den Rektor. Erfasst Klassen, Lehrer, Faecher, Raeume + Constraints und ruft einen Timefold-basierten Solver auf, um einen konfliktfreien Wochenplan zu produzieren.

Architektur auf einen Blick

studio-v2 /stundenplan  (Next.js)
        │  HTTP über Next.js Proxy /api/school/*
        ▼
school-service  (Go/Gin, :8084)
        │  ─ CRUD Stammdaten + Constraints + Solutions in PostgreSQL
        │  ─ Fire-and-forget Trigger an Solver
        ▼
timetable-solver-service  (Python/FastAPI + Timefold, :8095)
        │  ─ Liest Problem aus PG, rechnet im Worker-Thread
        │  ─ Schreibt Lessons direkt nach tt_lesson
        ▼
PostgreSQL  (Schema `public` in `breakpilot_db`)
        24 Tabellen: 7 Stammdaten + 15 Constraints + tt_solution + tt_lesson

Module

Bereich	Doku
Architektur + Datenmodell	DB-Schema, Ownership-Modell
Constraints	15 Constraint-Typen, hard/soft Semantik
Solver-Tuning	Timefold-Konfiguration, Zeit-Budgets
Export	CSV, ICS, Drucken

Status

Phasen 1-3 + 5-8 fertig (Stand 2026-05-22, Phase 4 Untis übersprungen).

24 DB-Tabellen, alle 22 CRUD-Endpoints + Solve + Export-Endpoints live
Frontend: 9 Tabs (Plan + 7 Stammdaten + Regeln), 15 Constraint-Editoren, Wochengrid mit Pin-Funktion, 3 Perspektiven (Klasse/Lehrer/Raum)
Tests: 73 Go + 36 Playwright + 4 Export-Unit-Tests

Offene Punkte

Phase 4 (Untis-Import) — verschoben, kein Kunde fordert es aktuell
Seed-Daten fuer Demo-Schule
Echte Auth-Integration ablöst Dev-Bypass
