fix(residential): mobile card list alongside the desktop table

Both the residential-clients and residential-interests pages rendered
plain HTML <table>s with 5–6 columns directly. At 390px viewport the
header columns clipped at the right edge — "Sour..." for the clients
page, no header for the interests page either.

Adds a parallel mobile card list:
  - <table> stays inside `hidden lg:block` (unchanged at lg+)
  - new card list inside `lg:hidden` mirrors the row data:
    - Clients: name + status pill on top, then email · phone ·
      residence · source as a wrap-friendly meta row.
    - Interests: stage label as headline, updated-at on the right,
      preferences (line-clamp-2) and notes (line-clamp-1) below,
      source small at the bottom.
  - Each card is a Link to the detail page (matching the row click
    target on desktop).
  - Empty + loading states render as a centered card on mobile.

This is the same `hidden lg:block` / `lg:hidden` pattern used for the
main /clients and /interests pages. Doesn't refactor to the full
DataView primitive (would mean rebuilding the residential data layer
on TanStack Table) — keeps the change tightly scoped to the visible
output.
