feat(ci): add scheduled data collection every 15 minutes

- Updated GitHub Actions workflow to run data collection tasks every 15 minutes using cron syntax.
- Added new schedule trigger alongside pull request trigger for continuous monitoring.
- Enhanced CI pipeline for both frontend and backend tests with separate tasks for each.
- Introduced concurrency control to avoid overlapping executions on the same branch.
