feat(sub12a): res.company.x_fc_default_recipe_editor setting

Per-company default for which editor opens for new recipes / recipes
with preferred_editor=auto. Defaults to 'tree' to preserve existing
behavior. Surfaces in Settings → Fusion Plating → Recipe Editor.

Naming follows the existing x_fc_* convention used throughout
res_company.py for company-level Fusion Plating defaults.
