AAP-79142 fix: resolve SonarCloud security rating C (#16503)

fix: resolve SonarCloud security rating C (AAP-79142)

Replace regex-based substring checks with plain `in` operator in awxkit
page.py to eliminate ReDoS vulnerability (python:S5852). Remove stray
empty Pipfile that triggered missing lockfile warning (text:S8565).
