Switch integration test deployment to httpd mode

Deploy CTS under Apache httpd on port 8080 to match the production
runtime, instead of Flask's built-in dev server on port 5005.

- Add a cts-config ConfigMap with two files:
  - config.py: ProdConfiguration (AUTH_BACKEND=noauth, PostgreSQL URI)
    so init_config loads it via the file-based path without needing
    CTS_DEVELOPER_ENV.
  - httpd.conf: minimal Apache + mod_wsgi config listening on 8080.
    ServerRoot is /etc/httpd so LoadModule paths resolve correctly.
    All writable paths (PidFile, Mutex, ErrorLog) go under /tmp/httpd
    which the container creates at startup, avoiding permission issues
    under OpenShift restricted-v2 SCC.
- Mount the ConfigMap at /etc/cts (read-only) in both the migration
  init container and the main cts container.
- Override the main container command to mkdir -p /tmp/httpd/run then
  exec httpd -DFOREGROUND -f /etc/cts/httpd.conf, bypassing the image
  default start_cts_from_here script which hardcodes CTS_DEVELOPER_ENV=1.
- Remove CTS_DEVELOPER_ENV and SQLALCHEMY_DATABASE_URI env vars from
  both containers (configuration now comes from the ConfigMap file).
- Update all port references from 5005 to 8080: Service port/targetPort,
  containerPort, readinessProbe, livenessProbe, and CTS_URL in the
  run-tests step.

Fixes #73
