Subject: [PATCH] fix: resolve SSE realtime ERR_INCOMPLETE_CHUNKED_ENCODING
 error

Add dedicated nginx location block for /api/realtime with:
- proxy_buffering off to prevent response buffering
- gzip off to avoid chunked encoding issues
- proxy_read_timeout 86400s for long-lived SSE connections
- Connection '' instead of 'upgrade' for SSE protocol
