⚡ Bolt: Prevent unnecessary re-renders in SessionDrawer

[parvezk]

💡 What: Replaced a useEffect hook that reset the message and sent states when the session.id prop changed, with a conditional render-phase state update.
🎯 Why: The previous implementation caused an unnecessary secondary render cycle every time a user switched between sessions because useEffect executes asynchronously after the initial render.
📊 Impact: Eliminates a duplicate render cycle when switching sessions.
🔬 Measurement: Verify by switching between active sessions in the dashboard UI and checking the render cycle using React dev tools; only one render should occur for a session switch.
