chore(awareness-service): bump axios floor to a non-vulnerable release

The declared range was ^1.6.7 - a stale floor that permits axios versions with
known CVEs. The lockfile already resolved to 1.13.6 (past the relevant fixes);
raise the declared floor to ^1.13.6 so the range itself can no longer resolve
to a vulnerable version.
