[plasma/libplasma] src/plasma: Drop Applet::globalConfig

Git commit a50b960182ac2f95b9a2f336c99bd388055c943e by Nicolas Fella.
Committed on 20/07/2026 at 22:24.
Pushed by nicolasfella into branch 'master'.

Drop Applet::globalConfig

This isn't called anywhere, except for scripting, so it doesn't seem to do anything.

The documentation also doesn't match the code wrt which config file is used.

We do want a feature that allows to define default values per applet type, but
this is just dead code
