test(screenshots): restore screenshot-neutrality after the determinism refactor

The determinism conversion silently dropped/renamed screenshots vs the committed
baselines, so CI flagged ~35 baselines as "removed". Restore them:

- pl_editor-*: re-add the "pl_editor-" prefix the conversion dropped (5).
- Buffer screenshots that lost their path: (eeschema draw-wires/loaded-css,
  pcbnew draw-lines/loaded-css, pcbnew-move, dark-mode, eeschema-crosshair,
  aui-resize) re-add path:'test-results/<name>' so they SAVE and still feed the
  in-test pixel-diff analysis (17).
- Dropped animating/loading captures re-added via stableShot / raw screenshot:
  timer-03/05/06, dialogs-timer-running/started, wxgrid-02/03, 01-loading (7).

Delete 5 obsolete wizard baselines (eeschema/gerbview/pl_editor/symbol_editor/
generic -wizard-00-initial): every app is now seeded to bypass the first-run
setup wizard (that was the point of removing the wizard for/if loop), so those
states are no longer produced — pl_editor.spec asserts "no wizard appears"
instead.

Net: every committed baseline has a producer again (0 "removed"); determinism
guard green; affected specs pass (e2e 40, kicad 12) and emit the restored PNGs.
