Migrate `Project` endpoint from `data` to `api`

[ZibanPirate]

Description

Since we have an API server now, the static data.dzcode.io is not needed, as a first step to migrating it to API, we start with the Project endpoint.

Check List

1. [ ] Create Project controller and endpoint with OpenAPI specs
2. [ ] Create Project repository that get data from both ./data folder & Github service
3. [ ] Update ./web and ./mobile code to use the new ./api endpoint

Additional Comments

once all models are migrated to ./api, we can decommission data.dzcode.io cc @CA1R7 ;)
