bug: mise doesn't read global settings.toml file anymore, but home-manager still puts settings there

[duckpuppy]

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• I have searched the existing issues

Issue description

The mise module writes it's global settings to settings.toml. This file is no longer read by mise. Settings should instead go inside the user's global config.toml under a [settings] header.

See https://mise.jdx.dev/configuration.html#settings-mise-settings
