Fix remaining review threads on the alts search controls

- Disable keyboard tracking on the depth and window spin boxes so typing a
  two-digit value sends one search, not one per digit.
- Reload the user under investigation on a filter change instead of reading
  the search box, which could switch to a name never submitted.
- Keep a chip's last match count while it is unchecked; the server omits
  unchecked match types, so the label used to drop to "(0)".
