fix(FN-944): activate projects after registration in dashboard API

- Fix project registration endpoint to set status to 'active' after creating a project
- Ensure newly registered projects are immediately operational instead of stuck in 'initializing'
- Add comprehensive tests for project route activation behavior including status transitions
