3 people b564f2ca9c fix(layers): identify the Background by structure, never by its English name (#4036) ...

Photoshop's Background is the bottom layer of a file without transparency: a pixel layer that is
transparency- and position-locked, whatever the file's language calls it ("Hintergrund", "背景",
"Arrière-plan"). We matched the name "Background" in compose (deep / shallow knockout), the
engine (cut/clear, merge visible, transforms, warps, distort, erasers, styles, masks, crops,
straighten, smart-object unpack) and the UI (Properties, layer row, tab title), so a localized
file's deep knockout revealed transparency instead of the Background.

- `Document::background` / `background_mut` / `is_background` and `Layer::has_background_traits`
  in the doc model replace every name check; `extra_cmds::background_to_layer` is the one
  "Background → Layer 0" conversion.
- PSD import marks the bottom record position-locked when it is transparency-protected and has
  no transparency channel, with or without an `lspf` block. Affinity import and HDR Toning now
  lock the Background's position like every other place that creates one.
