feat(46-03): update 4 node files for full-bleed content (Annotation, Array, AudioInput, ConditionalSwitch)

- Remove header props (title, customTitle, comment, etc.) from BaseNode calls
- Apply full-bleed content pattern with contentClassName
- Replace dashed border empty states with subtle fills (bg-neutral-900/40)
- Move floating UI elements to absolute positioning

Part of batch update for all 21 remaining node files.
