fix: preserve navigator search commands (#1140)

Navigator search treated Escape as either modal close or query reset,
which left no way to return to command mode while keeping the filtered
row set. `/` also rebuilt search mode by clearing the query, so a user
could not resume editing the same filter after backing out.

Make Escape leave search focus only, reserve command-mode Escape for
closing the picker, and let `/` refocus the existing query. The footer
now lists the shortcuts for the active mode so command keys are not
advertised while text input owns them.
