refactor(settings): draw the About card from floret-kit SettingsRecipes

Calendula's bespoke About card was the floret-kit components.AboutCard recipe in
disguise — logo + name/author, a row of equal-width outlined links, and a
full-width tonal highlight link. Replace the hand-rolled layout with the kit
recipe, supplying Calendula's logo (AppLogo, app-local) and its source
(ic_gitea, via vectorResource) / licence / support links as AboutLinks. Drop the
now-unused button/icon imports.

Calendula's language picker keeps its app-local form (it uses a custom header
the generic LanguagePickerRow recipe doesn't carry).

Compile + unit tests + lintDebug green.
