lukaszraczylo 38b3786942 HTTP and SSE dead client fix ...

Fix 1: HTTP Server timeouts (service.go)
  - Added IdleTimeout: 120s - closes idle keep-alive connections
  - Added ReadTimeout: 30s - prevents hung connections waiting for request data

  Fix 2: SSE dead client cleanup (broadcaster.go) - This was the real leak
  - Bug: When Write() failed on a disconnected client, it just logged and continued - the dead client stayed in the clients map forever
  - Effect: Dead clients accumulated and every Broadcast() call would try (and fail) to write to them
  - Fix: Now tracks failed writes and removes dead clients from the map

  The SSE bug was likely the main cause. Every time a browser tab closed or connection dropped, the client stayed registered. On each broadcast (processing status updates happen frequently), it would try to write to dead connections, fail, but never clean up.
