Companion: wire real Lottie assets — the always-sleeping cat

- LottiePlayer now auto-crops each asset to its content bbox (union getBBox
  across 6 frames -> square viewBox), so stock files with empty artboard
  padding fill the badge instead of floating tiny in the middle.
- Wire sleeping-cat.json to every mood: she's always asleep in the corner yet
  still mumbles tips and cheers through the bubble. napping hardcoded true so
  she keeps the calm sway + drifting zzz even while "talking".
- happy-dog.json parked in the folder as an awake-mascot alternate.
- Enable resolveJsonModule for the JSON imports.
