feat(web): topbar/nav cleanup batch (items 10-13)

Item 10: remove the disabled decorative topbar search input (each page
has its own working search); CSS rule and media-query reference removed.
Item 11: menu/title renames — 服务器 -> 节点管理, 客户与订阅 -> 用户订阅,
转发与节点 -> 入站&出站, 设置与运维 -> 设置 (nav, TITLES/breadcrumb and
cross-references synced); the chains page add button is now 添加入站 and
its count reads N 个入站; the 安装与命令 page is merged into 设置
(commandsHTML block between the settings grid and the jobs table) and
the page itself is removed from nav, PAGES, TITLES, load() and the view
map — an old #commands hash now lands on the SPA's standard overview
fallback.
Item 12: remove the system page's 最近活动 panel (rendering and its
audit label map plus orphaned CSS); backend audit records untouched.
Item 13: the settings jobs table gets the w-jobs treatment — ID, status
and time cells never wrap, compact row padding, and the error column is
capped at 22% width so an empty error column no longer balloons.

Also fixes a class collision from the item-8 batch: the exit-mode
segmented control is renamed .seg -> .segctl so it no longer draws a
border box around the system page info-bar segments.
Golden re-captured: the only diff is the served index HTML inside
errors.badSubscription, audited character by character as exactly these
renames and removals.
