[Bug] Emotes from Unity client not visible on mobile

### Platform
Mobile (iOS and Android)

### App Version
Not specified

### Device Information
Not specified

### Issue Description
When Unity client users perform emotes, those emotes are **not visible** to mobile users. The Unity user appears to be standing still from the mobile perspective, while the emote animation plays normally on their Unity client.

This affects both DCL Worlds and Genesis City locations.

### Expected Behavior
Emotes should be synchronized across all platforms. When a Unity client user performs an emote, mobile users should see the same emote animation playing on that user's avatar.

### Steps to Reproduce
1. Have one user on Unity client and another on mobile app in the same location
2. Unity client user performs any emote
3. From mobile perspective, Unity user appears to not be emoting (standing still or in default state)
4. From Unity perspective, the emote plays correctly

### Occurrence
Consistent based on user report

### Related Issues
- #1815 - Unity client avatars not visible on mobile (cross-platform avatar spawning)
- #1864 - Users appear stacked in one spot (cross-platform position sync)
- #1706, #1759, #1767 - Avatar orientation/animation sync issues between platforms
- #1912 - Mobile shows fewer users than Unity (potential rendering cap)

This appears to be another cross-platform avatar state synchronization issue, specifically affecting emote/animation state replication between Unity and mobile clients.
