Fixes delayed viewport fitting on server join/init (#93065)

## About The Pull Request

#91419 removed change_view in mob login for un-inited clients, which
leaves 1 second delayed fit_viewport calls from
attempt_auto_fit_viewport as the only way for new clients to adjust
their viewport from the default square (which is also only ran once all
subsystems finish initializing).
Just calling apply() after applying our prefs to the view_size is enough
to make it work, also we don't need the said second delay in
attempt_auto_fit_viewport anymore either.
