Add loadOnFocus to initSearchPicker; asset search shows recent by defaulterdgeist-revive-events

initSearchPicker's input handler has always short-circuited on an empty
term -- correct for every existing picker, none of which want results
appearing before anything's typed. The asset picker does want exactly
that (show the last few uploaded images without requiring a search
first), so this adds an opt-in loadOnFocus option instead of changing
the shared default: it fires once when the input gains focus with no
term yet, reusing the same request/render path a real search uses
rather than a separate code path. The AJAX call itself was pulled out
into a named runSearch function so both triggers could share it without
duplicating the success/render logic.

RelatedAssetsController#search now treats a blank term as "show the
most recently created, unattached images" (limit 5) rather than
returning nothing, matching the new client behavior. A real search
term still returns up to 10 name-matched results, unchanged.
