chore(editor): delete legacy door/window presets UI (#339) (#343)

Retires the door/window-only `PresetsPopover`, its `presets-context`
adapter, and the `PresetThumbnailGenerator` ahead of the unified preset
system landing via the items catalog. Drops the public exports
(`PresetsPopover`, `PresetsAdapter`, `PresetsTab`, `PresetsProvider`,
`usePresetsAdapter`) and the matching `presetsAdapter` prop / provider
wrappers on `<Editor>`, plus the `preset:generate-thumbnail` /
`preset:thumbnail-updated` event types in core. Door and window panels
now render the regular parametric inspector with no popover trigger;
`materialPreset` stays untouched.
