Subject: [PATCH] refactor(frontend): switch sub page theme icons to AntD
 primitives
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the three hand-rolled SVG theme icons (sun, moon, moon+star)
with AntD `<SunOutlined />`, `<MoonOutlined />`, `<MoonFilled />`
for the light / dark / ultra-dark states. Switch the theme `<Button>`
to use the `icon` prop instead of children so it renders the same
way as the language button. Drop `.toolbar-btn svg` CSS — no longer
needed once the icon comes from AntD.
