fix(1e): HC1 upgrade/restore tier calls now pass head_ref (multi-line edit miss)

Earlier perl substitution missed the multi-line upgrade and restore run_lifecycle_tier calls (still
passed `target` = VERSION env, None for !testme runs), so perform_upgrade got head_ref=None for
upgrade tier → re-checkout skipped → chaos redeploy of leftover prev checkout (vacuous prev→prev that
'passed' via the chaos-label move fallback).

Verified e2e on hedgedoc (install,upgrade; commit pending push):
  upgrade→PR-head: head_ref=09bf4d54 chaos-version=09bf4d54 version=3.0.9+1.10.7→3.0.10+1.10.8
deploy-count=1, install/upgrade=pass, clean teardown. The chaos-version label deterministically
matches head_ref — direct proof PR-head code was deployed.

+- Debug print at main() head_ref capture showed `head_ref='09bf4d54...'` (correct hash), but
+  perform_upgrade printed `head_ref=None`. Root cause: my earlier perl regex to swap `target →
+  head_ref` in the four `run_lifecycle_tier` call sites only matched the SINGLE-LINE form; the
+  multi-line `upgrade` and `restore` calls (lint-wrapped) still passed `target` (which is the VERSION
+  env, None for !testme runs). So perform_upgrade got head_ref=None for upgrade tier → re-checkout
+  skipped → chaos deploy of whatever leftover checkout (prev tag from deploy_app) → vacuous prev→prev
+  chaos redeploy that "passed" via the chaos-label move fallback.
+- Fixed: explicit Edit on the two multi-line calls so they now pass `head_ref` consistently
+  (`recipe`/`"upgrade"|"backup"|"restore"`, `repo_local`, `domain`, `meta`, `head_ref`, `op_state`).
+  grep confirms all 4 tier calls pass head_ref. compile OK.
+- Net effect now: head_ref reaches perform_upgrade → recipe_checkout_ref(head_ref) restores PR-head
+  before chaos deploy → after.chaos == head_ref → assert_upgraded match succeeds non-vacuously.
