fix(settings): run batch updates per-tool and lock actions while busy

Update All previously sent every tool to the backend as one script, where
set -e (or errorlevel on Windows) aborts the whole batch on the first
failure, skipping the rest and not refreshing versions for tools that did
succeed. Run each tool as its own call instead: failures are isolated,
each tool's version refreshes as soon as it finishes, and the result is
summarized in a toast (success / partial / failure) listing which tools
failed.

Also derive an isAnyBusy flag and disable all install/update buttons,
the refresh button and the WSL shell selectors while any action is
running, so users can't trigger concurrent global npm/pip writes.

Add the toolActionPartial i18n key (zh/en/ja).
