fix: make insermode=conserve for sites meeds, mycraft, and space_templates - MEED-9953 - #3803

Before this fix, when removing a page in the navigation of site meeds, or mycraft or in space template, the page is recreated at startup
To prevent this, we change the default configuration for importMode to use "conserve", so that removed page is not recreated.

Resolves #3803
