fn-1.8 End-to-end testing

Description

Fix WebSocket chat tests to use proper async WebSocket testing approach (matching existing test_transcripts_rtc_ws.py pattern) instead of TestClient which has event loop issues.

Current State

• Backend endpoint implemented: server/reflector/views/transcripts_chat.py
• Frontend components implemented: useTranscriptChat.ts, TranscriptChatModal.tsx
• Integration complete: chat components added to transcript page
• Basic tests exist but fail due to TestClient event loop issues

Acceptance

• All WebSocket chat tests pass using proper async approach (httpx_ws)
• Tests validate: connection, message protocol, context generation, error handling
• Tests use threaded server pattern matching test_transcripts_rtc_ws.py
• No event loop or asyncio errors in test output

Done summary

Fixed WebSocket chat tests by switching from TestClient to proper async testing with httpx_ws and threaded server pattern. All 6 tests now pass without event loop errors.

Changes

• Rewrote all WebSocket tests to use aconnect_ws from httpx_ws
• Added chat_appserver fixture using threaded Uvicorn server (port 1256)
• Tests now use separate event loop in server thread
• Matches existing pattern from test_transcripts_rtc_ws.py

Tests Passing

All 6 tests now pass:

1. test_chat_websocket_connection_success - validates WebSocket connection and echo behavior
2. test_chat_websocket_nonexistent_transcript - validates error handling for invalid transcript
3. test_chat_websocket_multiple_messages - validates handling multiple sequential messages
4. test_chat_websocket_disconnect_graceful - validates clean disconnection
5. test_chat_websocket_context_generation - validates WebVTT context generation
6. test_chat_websocket_unknown_message_type - validates echo for unknown message types
