feat: lokaler MCP-Server, Phase 2 (Write-Tools + Bestätigungsdialog + Lesson-Plans)

Browse Source 
Neue Write-Tools create_time_entry, create_grade_entry und
update_student_group_assignment schreiben nie direkt: jeder Aufruf zeigt
zuerst einen menschenlesbaren Bestätigungsdialog (bestehender
ConfirmDialog, über Dispatcher.UIThread aus dem Pipe-Session-Thread
angezeigt) und schreibt erst nach Bestätigung, mit 2-Minuten-Timeout
gegen eine hängende Session. Zusätzliches Read-Tool get_lesson_plans.

create_note bewusst nicht umgesetzt (kollidiert mit dem bestehenden
Dokumentations-Ausschluss aus Phase 1), create_lesson_plan/
update_lesson_plan wegen der Modellkomplexität von Lesson zurückgestellt
(siehe TODO.md 4.5.26).
