Problem:
- Text input area caused BOTTOM OVERFLOWED BY 135 PIXELS when keyboard opened
- Input bar overlapped with call control buttons
- Sent messages were not displayed on screen (only SnackBar feedback)
Solution — split into two distinct layouts:
1. Call Mode (default):
- Full-screen call UI: avatar, waveform, duration, large control buttons
- Keyboard button in controls toggles to chat mode
- No text input elements — clean voice-only interface
2. Chat Mode (tap keyboard button):
- Compact call header: green status dot + "iAgent" + duration + inline
mute/end/speaker/collapse controls
- Scrollable message list (Expanded widget — properly handles keyboard)
- User messages: right-aligned blue bubbles with attachment thumbnails
- Agent responses: left-aligned gray bubbles with robot avatar
- Input bar at bottom: attachment picker + text field + send button
Message display:
- User-sent text/attachments tracked in _messages list, shown as bubbles
- Agent responses sent back via LiveKit data channel (topic='text_reply')
from voice-agent → Flutter, displayed as assistant bubbles
- Auto-scroll to latest message
Voice-agent change (agent.py):
- After session.say(response), publish response text back to Flutter via
ctx.room.local_participant.publish_data() with topic='text_reply'
- Flutter listens for DataReceivedEvent to display agent responses
