Vuetify's auto card-stack was too verbose (one subscription filled the whole
phone screen) and the expanded sources still needed lateral scroll. Replace it
below 600px (useDisplay) with a custom compact-card list: each subscription is
a 2-line card (name + health + expand chevron, then platform chips + sources
count + last activity) so several fit per screen. Expanding shows the action
row + each source as a STACKED SourceCard (new) — platform/url/enabled/last/
next/errors/actions laid out vertically, no horizontal scroll. The mobile
cards drive the same selected/expanded key arrays as the desktop data-table,
so selection and bulk actions are unchanged. Desktop keeps the v-data-table.
