feat(web): fold the search truncation total into the summary line

Replace the separate '已截断 · 共 N' pill with '显示 X / 共 N 处匹配 · K 个文件'
(and '显示 X / 共 N 个路径' for glob), mirroring the read card's '显示 X / Y 行',
so the retained count and the pre-cap total read as one clause instead of two
numbers that appear to disagree.
