VGA console: stop importing spice-html5's demo stylesheet, which restyled every button

spice.css sets body, *, button and canvas for the whole document. Bundled
into the App chunk since 43ebacd (deployed as v0.1.0-188), it turned every
button into a gradient pill, shifted 15% right and 8% up with a 150px
minimum width, broke the rail and header layout, and bordered every graph
canvas. The console is already styled by the .vga rules in styles.css.

The file is removed from the vendored copy, and a new web test fails on any
stylesheet import outside an allow-list.

+copied unchanged on 2026-10-09 (`src/`, `thirdparty/`). LGPL-3.0-or-later; the
 licence text is beside this file. It draws a VM's SPICE display into a canvas from a websocket
 carrying the raw SPICE stream — which is what Incus's VGA console websocket is — so Ham Lab's
 daemon bridges the two and this does the rest. Loaded lazily by `VgaConsole.tsx`, so the main
 bundle does not carry it. Not on npm in a current form (the `@spice-project/spice-html5`
 package stopped at 0.2.1 in 2019), hence the copy.

+Upstream's `spice.css` is deliberately **not** here. It is the stylesheet of spice-html5's
+demo page, with rules for `body`, `*`, `button` and `canvas` that apply to the whole
+document. It was copied and imported on 2026-10-09 and turned every button in Ham Lab into
+a gradient pill shifted off its place (v0.1.0-188 to -191). The console is styled by the
+`.vga` rules in `src/styles.css`; `scripts/test-css-imports.mjs` fails on any new
+stylesheet import that has not been looked at.
