CRITICAL: WebSocket background loop never starts

[Sszmentor]

Bug

server.py:356 calls asyncio.create_task(websocket_manager.connect()) but start_background_task() is never called. The WS manager connects but _background_loop (which reads messages, handles reconnects) never runs. Real-time subscriptions silently receive nothing.

Fix

Call websocket_manager.start_background_task() after connect, or merge connect+loop into one coroutine.

Also fix

• websocket_manager.py:261-265: WS auth sends POLYMARKET_PASSPHRASE for both secret and passphrase fields. Should use separate POLYMARKET_API_SECRET env var for secret.
• _background_loop uses asyncio.wait(FIRST_COMPLETED) which starves one channel under load. Use two separate tasks instead.
