migrate subtitle style config to CSS declaration shape

- Flat style keys (fontFamily, fontSize, hoverTokenColor, etc.) consolidated into subtitleStyle.css, secondary.css, and subtitleSidebar.css objects
- Hover token colors migrated to --subtitle-hover-token-color CSS custom properties
- Plugin app-ping now checks result.status (0=running, 1=stopped) to avoid treating transient failures as stopped
- Note-fields note type picker defaults to configured deck's note type before falling back to Kiku/Lapis
- New migration for legacy ankiConnect N+1 config paths
