Polymaker, Overture and eSUN presets move from brand subfolders to
BBL/filament/, matching BambuStudio's layout; their names and ids are
unchanged. Default filament lists keep pointing at presets that exist,
0.2 mm nozzles keep a default PLA, and user presets based on removed or
renamed presets still load. Generic SBS is no longer in the Bambu bundle;
new selections on those printers fall back to OrcaFilamentLibrary's
Generic SBS @System. The profile tool now recognises BambuStudio's new
filament id/name maps and support_recommended_params.json as data files.
