fix(api): keep file event streams alive

- Disable the Quart response timeout for authenticated file event streams.
- Send SSE keepalives more often to avoid idle proxy disconnects.
- Treat remote stream interruptions as reconnectable disconnects in watch output.
- Bump NanoShare to 1.26.0 and the standalone CLI to 0.4.1.
