fix(web-search-card): follow base rename kind->shape and view-drops-content

The base (feat/search-presenter) renamed the search result view's discriminant
from `kind` to `shape` and removed the view's `content` field (a UI without a
card now falls back to the raw tool/result content). Adapt the web consumer:

- searchCardModel switches on `result.shape`; SearchBlock's own `kind` prop is
  mapped from it.
- The truncation recovery footer reads the block's raw `content` (where the
  `Full … stored at …` locator now lives) instead of the removed view content.
- Fixture grep/glob views use `shape` and drop `content`; the recovery footer
  rides the raw tool/result text.
- Tests and the bilingual Agent Note follow the rename and the recovery source.
