release(v1.7.6-alpha): robust apply_update + manifest-override env var

apply_update frontend swap
  Transient EROFS on .198 (filesystem hiccup — root FS mounts with
  errors=remount-ro so a fleeting glitch can bounce /opt to RO for a
  moment) caught the pre-cleanup `rm -rf web-ui.new web-ui.bak` mid-
  stride and aborted the apply. Rewrote the swap to use a timestamped
  staging dir (web-ui.new.<ms>) and a timestamped old-copy path so
  nothing needs to be rm'd before the extract. After the new tree is
  mv'd into place, the previous rollback copy is rotated aside with a
  .<ms> suffix (best-effort) and this apply's old copy becomes the new
  web-ui.bak. If the final mv fails, the staged old is restored so
  nginx keeps serving.

handle_update_check manifest override
  handle_update_check takes the git path whenever ~/archy/.git exists.
  On the dev box (.116) that meant the Pull & Rebuild button was
  always the only option even though the manifest-path OTA was
  already wired via ARCHIPELAGO_UPDATE_URL. Now: if that env var is
  set, we skip the git detection entirely and use the manifest path.
  The regular fleet (no env var, no repo) hits the manifest branch
  naturally; beta dev nodes (repo + no env var) still get Pull &
  Rebuild; dev nodes with the env var explicitly set can finally test
  the manifest OTA end-to-end.
