fix: Handle emoji and special characters in mention notifications (#11857)

Browse Source 
Fixes notification display issues when user or team names contain emojis
and special characters. Previously, mention notifications would show
URL-encoded characters instead of properly formatted names with emojis.

  **Before:**
Notification: "John Doe: Hey @%F0%9F%91%8D%20customer%20support please
check this"

  **After:**
  Notification: "John Doe: Hey @👍 customer support please check this"
