Add GitHub Actions CI/CD workflow templates and dynamic coverage badge integration

- Introduced workflow templates for backend (`backend-tests.yml`), frontend (`frontend-tests.yml`), and end-to-end testing (`e2e-tests.yml`), including setup instructions in `.github/workflows/README.md`.
- Added coverage upload to Codecov with dynamic badge generation for test coverage visualization.
- Updated project `README.md` to replace static badges with placeholders for dynamic CI/CD badges.
- Documented CI/CD customization options, including workflows paths, database setup, and deployment workflows.

+# GitHub Actions Workflows
+
+This directory contains CI/CD workflow templates for automated testing and deployment.
+
+## 🚀 Quick Setup
+
+To enable CI/CD workflows:
+
+1. **Rename template files** by removing the `.template` extension:
+   ```bash
+   mv backend-tests.yml.template backend-tests.yml
+   mv frontend-tests.yml.template frontend-tests.yml
+   mv e2e-tests.yml.template e2e-tests.yml
+   ```
+
+2. **Set up Codecov** (optional, for coverage badges):
+   - Sign up at https://codecov.io
+   - Add your repository
+   - Get your `CODECOV_TOKEN`
+   - Add it to GitHub repository secrets
+
+3. **Update README badges**:
+   Replace the static badges in the main README.md with:
+   ```markdown
+   [![Backend Tests](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/backend-tests.yml/badge.svg)](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/backend-tests.yml)
+   [![Backend Coverage](https://codecov.io/gh/YOUR_ORG/YOUR_REPO/branch/main/graph/badge.svg?flag=backend)](https://codecov.io/gh/YOUR_ORG/YOUR_REPO)
+   [![Frontend Tests](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/frontend-tests.yml/badge.svg)](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/frontend-tests.yml)
+   [![Frontend Coverage](https://codecov.io/gh/YOUR_ORG/YOUR_REPO/branch/main/graph/badge.svg?flag=frontend)](https://codecov.io/gh/YOUR_ORG/YOUR_REPO)
+   [![E2E Tests](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/e2e-tests.yml/badge.svg)](https://github.com/YOUR_ORG/YOUR_REPO/actions/workflows/e2e-tests.yml)
+   ```
+
+## 📋 Workflow Descriptions
+
+### `backend-tests.yml`
+- Runs on: Push to main/develop, PRs affecting backend code
+- Tests: Backend unit and integration tests
+- Coverage: Uploads to Codecov
+- Database: Spins up PostgreSQL service
+
+### `frontend-tests.yml`
+- Runs on: Push to main/develop, PRs affecting frontend code
+- Tests: Frontend unit tests (Jest)
+- Coverage: Uploads to Codecov
+- Fast: Uses npm cache
+
+### `e2e-tests.yml`
+- Runs on: All pushes and PRs
+- Tests: End-to-end tests (Playwright)
+- Coverage: Full stack integration
+- Artifacts: Saves test reports for 30 days
+
+## 🔧 Customization
+
+### Adjust trigger paths
+Modify the `paths` section to control when workflows run:
+```yaml
+paths:
+  - 'backend/**'
+  - 'shared/**'  # Add if you have shared code
+```
+
+### Change test commands
+Update the test steps to match your needs:
+```yaml
+- name: Run tests
+  run: pytest -v --custom-flag
+```
+
+### Add deployment
+Create a new workflow for deployment:
+```yaml
+name: Deploy to Production
+on:
+  push:
+    branches: [ main ]
+    tags: [ 'v*' ]
+```
+
+## 🛡️ Security
+
+- Never commit secrets to workflows
+- Use GitHub Secrets for sensitive data
+- Review workflow permissions
+- Keep actions up to date
+
+## 📊 Coverage Reports
+
+With Codecov enabled, you'll get:
+- Coverage trends over time
+- PR coverage comparisons
+- Coverage per file/folder
+- Interactive coverage explorer
+
+Access at: `https://codecov.io/gh/YOUR_ORG/YOUR_REPO`
+
+## 💡 Tips
+
+- **PR checks**: Workflows run on PRs automatically
+- **Status checks**: Set as required in branch protection
+- **Debug logs**: Re-run with debug logging enabled
+- **Artifacts**: Download from workflow run page
+- **Matrix builds**: Test multiple Python/Node versions
