fix(app): replace Vuetify 2 legacy props with proper V3 API

Replace deprecated V2 props that were being silently ignored:
- v-layout → v-row, grid-list-md removed, xs → cols on v-col
- v-tooltip top → location="top", v-list dense → density="compact"
- v-app-bar app/scroll-off-screen → scroll-behavior="hide"
- append-outer-icon → append-icon, remove primary-title
- headline class → text-h6, remove wrap from v-row
