fix: setup wizard overwrites platform_toolsets saved by tools_command

The wizard and tools_command each loaded their own config dict. When
tools_command saved platform_toolsets (with MoA/HA disabled), the
wizard's final save_config() overwrote it with its own dict that lacked
platform_toolsets entirely — resetting everything to defaults.

Fix: pass the wizard's config dict into tools_command so they share the
same object. Now platform_toolsets survives the wizard's final save.
