F-139 — Architect (bug fix)

Bug

Admin /admin/logs/stream SSE connection drops with ERR_NETWORK_IO_SUSPENDED.

Root causes

1. Proxy (apps/admin/src/app/api/[...path]/route.ts): did not set X-Accel-Buffering: no, which causes intermediate proxies (nginx) to buffer the SSE stream and kill it.
2. Client (ServerLogViewer.tsx): connect() goes to reconnecting status on drop but never actually reconnects — no retry loop.
3. LogBroadcaster.stream(): dead code — never used by the SSE route (uses registerClient() instead).

Fixes

1. Proxy: add X-Accel-Buffering: no header; remove explicit Connection: keep-alive (default for HTTP/1.1).
2. Client: add exponential backoff reconnection loop (1s → 2s → 4s … max 30s).
3. Backend SSE endpoint already correct with proper headers.
