ci: consolidate test jobs into single workflow with npm caching

- Merge 3 parallel test jobs (backend/frontend/mobile) into one sequential job
- Remove dependency on dorny/paths-filter@v3 (replaced with git diff script)
- Add npm cache via setup-node to speed up dependency installation
- Downgrade Node.js from 24 to 22 LTS for stability
- Reduce checkout fetch-depth from full history to 2 commits
