fix(sidebar): move mascot chatbot outside framer-motion nav to fix click interaction

- Move MascotChatbot outside motion.nav to avoid framer-motion stacking context break
- Use fixed positioning with z-[9999] for reliable interaction
- Wrap sidebar return with Fragment for multiple root elements
- Add border tail to chat bubble with two-layer clip-path (outer border, inner fill)
- Fix tail direction to point bottom-left toward mascot
