feat(home): icon should render on the right of title when alignment='right' #3951

Context

PR #3947 recently added an alignment: 'left' | 'center' | 'right' option to home.content.component.vue. When alignment === 'right', the whole flex block (icon + title) is pushed to the right via justify-end, but the DOM order stays [icon][title], so the icon still visually sits on the LEFT of the title.

Expected behavior

When alignment === 'right', the icon should visually hug the right edge, matching the text alignment. Visually: [title] [icon].

Proposed fix

Add flex-row-reverse to the icon+title wrapper div when computedAlignment === 'right'. This must NOT be applied to other flex containers in the component (e.g. v-card-actions), which would flip button order.
