BC-5611 - add new create-task-endpoint

[wolfganggreschus]

Description

This pr is part of the migration of homework from Feathers to NestJS. There is an existing Task module in Nest where the logic for creating a new task (homework) should be implemented. The old create-homework procedure should be removed.
A part of this ticket should involve the frontend using the new endpoint.
