fix(filter): apply preset on full tile click and suppress i18n double-translate warnings

- Move preset apply handler from span.preset-name to div.filter-preset so
  clicking anywhere on the tile triggers the preset, not just the label text.
- Add whitespace heuristic in showToast() to skip translate() for plain
  messages that are already translated at the call site. This prevents
  i18next from logging 'Translation key not found' for pre-translated
  strings like 'Preset "name" applied'.
