feat(hub): drop the Search page title, add a Files refresh button

1. The "Search Files" <h2> is removed from the search page — it duplicated
   the nav and cost a line of vertical space on mobile. `search.title` is
   dropped from all ten locales (its only use).

2. A monochrome refresh button sits left of the Files breadcrumb home
   icon. It calls `onRefreshIndex` (re-fetch the group index from the
   node — the file list is a view over a cached copy with no other way to
   pull a fresh one), spins while in flight, and only renders where an
   `onRefreshIndex` is wired (the real group view, not the cross-group
   search results). New `refresh` icon; `group.refresh_index` in all ten
   locales.
