Mobile: same stacked treatment for the Admin + Moderation account cards

Extends the .profile-account-card pattern to the remaining compact account
lists so they all behave consistently on phones:

- Admin lists (whitelist/blacklist/editors): use the shared
  .profile-account-card / __actions classes (was bespoke responsive utilities;
  now full-width equal-width action buttons on mobile like the others).
- Moderation overrides: the summary+actions row (a nested flex inside an
  already-padded card) uses a new padding-less .profile-account-card__row
  variant so it stacks on phones too.

The account switcher (single tap-button with a column meta-stack) and DM
conversation rows (tap-to-open, no action buttons) are already mobile-friendly
and structurally different, so they're intentionally left as-is.
