feat(config): reorganize settings window and move annotation colors to subtitleStyle

- Reorganize Configuration window into Appearance, Behavior, Anki, Input, and Integration sections
- Add AnkiConnect-backed deck, note-type, and field pickers in the Anki section
- Add click-to-learn keybinding controls
- Move known-word and N+1 highlight colors to subtitleStyle.knownWordColor / subtitleStyle.nPlusOneColor; legacy ankiConnect.knownWords.color and ankiConnect.nPlusOne.nPlusOne keys still accepted with deprecation warnings
- Add deckNames, modelNames, modelFieldNames, and fieldNamesForDeck methods to AnkiConnectClient
- Mark discordPresence.presenceStyle as an enum in the config registry
