fix(spotlight): activate first result before on_submit in entry accept

_on_entry_accept checked _active_plugin_entry before _current_results.
Keyword plugins (emoji, clipboard) are always active when prefix typed,
so on_submit (no-op base) swallowed Enter before result.action() fired.

Now results are checked first. on_submit only as fallback when no results.
