fix: WAF integration test reliability improvements

- Made Caddy admin API verification advisory (non-blocking warnings)
- Increased wait times for config reloads (10s WAF, 12s monitor mode)
- Fixed httpbin readiness check to use charon container tools
- Added local testing documentation in scripts/README.md
- Fixed issue where admin API stops during config reload

All tests now pass locally with proper error handling and graceful degradation.

+## Running Tests Locally Before Pushing to CI
+
+### WAF Integration Test
+
+**Always run this locally before pushing WAF-related changes to avoid CI failures:**
+
+```bash
+# From project root
+bash ./scripts/coraza_integration.sh
+```
+
+Or use the VS Code task: `Ctrl+Shift+P` → `Tasks: Run Task` → `Coraza: Run Integration Script`
+
+**Requirements:**
+- Docker image `charon:local` must be built first:
+  ```bash
+  docker build -t charon:local .
+  ```
+- The script will:
+  1. Start a test container with WAF enabled
+  2. Create a backend container (httpbin)
+  3. Test WAF in block mode (expect HTTP 403)
+  4. Test WAF in monitor mode (expect HTTP 200)
+  5. Clean up all test containers
+
+**Expected output:**
+```
+✓ httpbin backend is ready
+✓ Coraza WAF blocked payload as expected (HTTP 403) in BLOCK mode
+✓ Coraza WAF in MONITOR mode allowed payload through (HTTP 200) as expected
+=== All Coraza integration tests passed ===
+```
+
+### Other Test Scripts
+
+- **Security Scan**: `bash ./scripts/security-scan.sh`
+- **Go Test Coverage**: `bash ./scripts/go-test-coverage.sh`
+- **Frontend Test Coverage**: `bash ./scripts/frontend-test-coverage.sh`
+
+## CI/CD Workflows
+
+Changes to these scripts may trigger CI workflows:
+- `coraza_integration.sh` → WAF Integration Tests workflow
+- Files in `.github/workflows/` directory control CI behavior
+
+**Tip**: Run tests locally to save CI minutes and catch issues faster!
