fix(docs-scripts): pin LC_ALL=C so SCRIPTS.md ordering is deterministic

CI's drift check failed on pure ordering noise: the generator's `sort`
collated rows and caller lists by the ambient locale (en_GB.UTF-8 on the
dev box that committed the file, C in the CI container), so `-` vs `/` and
`-` vs `s` ordered differently (e.g. theme-update vs themes-prebuild,
caller-list order). Force LC_ALL=C in the generator and regenerate
docs/SCRIPTS.md in that collation, so the committed copy and any
regeneration — dev box or CI — are byte-identical.
