Add dummy data seeding for dev experience

[Luminagitur]

Motivation

Currently, this project has no dummy data seeding. Every time you develop or debug the frontend/backend, you have to create the data manually. This makes development inconvenient and can be improved by adding a dummy data seed with Prisma.
