Add a search bar on the recent activity page that allows users to
search across all content within the current space — messages, threads,
classifieds, goals, and calendar events. Uses createSearch from Welshman
with fuse.js for client-side fuzzy matching. When the search field is
empty, the normal recent activity view is shown. Matching activity items
are filtered inline; individual event matches can be clicked to navigate.
