docs(skills): apply v1-name fix to gmail/gcal tools

The gmail/gcal Phase 4 restart blocks and uninstall one-liners
still hardcoded `com.nanoclaw` / `restart nanoclaw`, so on a v2
install they would fail with "no such service" or kick the
wrong unit.

Phase 4 restart now uses the canonical
`source setup/lib/install-slug.sh` + `$(launchd_label)` /
`$(systemd_unit)` pattern with the standalone `Run from your
NanoClaw project root:` lead-in. Uninstall one-liners switch
to the inline-subshell form
`"$(. setup/lib/install-slug.sh && systemd_unit)"`.

(Folds in #2489's v2-alignment changes to the same two files;
the deferral noted in the original PR body is no longer needed
now that #2489 has merged.)
