fix(redis): make completion menu follow typing

The result used filter:false + validFor, which CodeMirror treats as
mutually exclusive — validFor is ignored, so the list froze and the
selection did not move while typing. Build the result with the default
built-in filter so typing narrows the list and moves the selection.
