fix(i18n): restore count separators in terminal theme picker for CJK locales (#9935)

The theme picker count row concatenates "Showing {count}" directly with
the " of {{value0}}" fragment. The ko/ja/zh translations dropped the
fragment's leading separator, so the shown and total counts fused
(e.g. Korean rendered "표시 중 3030 중" instead of "표시 중 30/30").

Restore a slash separator for the total-count fragment and the leading
space for the search-match fragment in ko/ja/zh, in both the runtime
catalogs and the key-override sources so catalog regeneration keeps the
repaired values. Add a regression test covering both fragments.
