feat(config): add subtitle CSS editor, nPlusOne.enabled flag, and fix se

- subtitleStyle.css / subtitleStyle.secondary.css replace flat style fields in the settings window
- ankiConnect.nPlusOne.enabled gates known-word cache independently of knownWords.highlightEnabled
- Settings search now covers all categories, narrows on multi-word terms, and hides editor-owned fields
- Default note-type picker to Kiku then Lapis; rename isLapis.sentenceCardModel default to "Lapis"
