Log Instead of Showing Info and Substitution Dialogs When Opening a BambuStudio Project

Every BambuStudio project opened with a "BambuStudio Project" info dialog
(or, from BambuStudio 2.8.2, one saying the file is newer than the
compatible version and to update the software), followed by the
configuration-substitution dialogs for the project and its embedded
presets. None of them asks anything and all of them fire for every
BambuStudio file.

For BambuStudio projects (untagged files newer than 2.3.2, the existing
test) log the version with the unrecognized settings, and each replaced
value, instead. The geometry-only, invalid-values and G-code safety
dialogs stay, and other 3MFs are unchanged.
