feat(settings): surface the console color toggles as checkboxes

Add "Color accents" and "Text colors" checkboxes under the effects section
(both layout variants) so the console output display prefs are discoverable
outside the console toolbar. They mirror the toolbar buttons — bound live to
the ConsoleTab statics and written through to settings on change.

Unlike scanline/theme-effects they carry no GPU cost, so a small helper closes
the effects row's BeginDisabled(low_spec), draws them on their own always-
enabled row, and reopens it for the acrylic sliders (net-balanced). Adds
console_accents / console_text_colors labels + 8 translations; the tooltips
reuse the existing toggle keys.
