components: add AboutCard + LanguagePickerRow settings recipes

AboutCard — logo slot + app name/author, a row of outlined link buttons and an
optional tonal highlight link (each opens its URL). LanguagePickerRow — a
GroupedRow that opens the full-screen language picker, backed by core-locale's
AppLanguage. Both parameterized so each app keeps its own strings, logo and row
icon. Adds the components -> core-locale dependency.
