* fix: locks need to be acquired and released using the same session * feat: only allow a single storage template operation at a single time this has been added to avoid possible rare race conditions where two files are moved at once to the same path with the same name, causing our duplicate iterator to not detect them and therefore both files will have the same name and overwrite eachother
