chore(simplify): trim SHA-rot comments + harden TENANT_HOST scheme/port stripping

Simplify pass on top of the canary fix:

- Drop the three CP commit SHAs from comments — issue #2090 covers
  the audit trail, SHAs would rot.
- Pull the inline `900` into TLS_TIMEOUT_SEC=$((15 * 60)) so the
  bash mirrors the TS side (15 min) at a glance.
- TENANT_HOST extraction now strips http(s) AND any port suffix, so
  getent doesn't silently fail on a ws://host:443 style URL.
- sed-redact Authorization/Cookie out of the curl -v dump, defensive
  against future callers adding an auth header to this probe.

Pure cleanup; no behaviour change to the happy path.
