Adding Concurrency with `cancel-in-progress` to GitHub Actions CI to Cut Build Minutes

Developers integrated the concurrency feature with cancel-in-progress into GitHub Actions workflows for projects like lavanderia-crm and tvview. This update automatically aborts older runs on the same branch when new pushes occur, preventing overlapping executions and resource competition. By eliminating duplicate CI and E2E test runs, these changes reduce wasted Action minutes by approximately 30% on active PRs, ensuring faster pipelines and preventing flaky test artifacts caused by multiple parallel jobs fighting for resources.
