feat: implement live emoji reactions

[Sai-Adithya-M]

Description

Implemented real-time emoji reactions in rooms, allowing users to express themselves instantly during live audio sessions. This includes the UI for sending reactions (ReactionBar) and displaying them (ReactionFloater), as well as the controller logic for broadcasting updates via LiveKit.

• New Feature: Added floating animated emoji reactions (❤️, 😂, 👏, 🔥, 😮, 🎉).
• Logic: Updated SingleRoomController to handle local optimistic updates and LiveKit broadcasting.
• Fixes: Resolved regression in AuthStateController caused by removed debugging files.
• Optimization: Cleaned up code and removed unused platform files to ensure a minimal diff

Fixes #744

Type of change

• New feature (non-breaking change which adds functionality)
