fix: company save no longer deactivates on partial updates

The checkbox-to-0 logic was running on every save including partial
saves (e.g. bot-config only sends config_json). This silently set
is_active=0 every time the bot config was saved.

Now checkbox defaults only apply when 'name' is present in the data,
which is the case only for full company-form saves.
