Refresh a CLI Project's Filament Settings From Their System Presets (#16038)

* Refresh a CLI Project's Filament Settings From Their System Presets

The CLI loads a project's printer and process settings as the GUI does,
taking every key the project does not list as changed from the current
system preset, but it kept the stored filament values. A project saved
before a profile update then sliced with old filament values on the
command line and with the current ones in the GUI.

Every project filament that no loaded filament replaces is now resolved
by its system preset name and fed to the filament merge the up-to-date
path already uses, which keeps the keys listed in
different_settings_to_system and maps per-variant values onto the
preset's variants. This covers a plain run, --uptodate without
--uptodate-filaments, and the slots --load-filaments leaves empty. The
merge tells refreshed entries from loaded ones per entry instead of by
the global loaded-filament count, and the entries are kept in slot
order. A project filament saved under a name the presets have since
split per nozzle is resolved through the name conversion the GUI uses,
which PresetBundle now exposes.

* Check the Project Refresh Test's Result Directly

Shellcheck SC2181: test the checker's exit status in the if instead of
reading $? afterwards.
