aio-interface: fix nginx reverse proxy read timeout blocks AIO from starting consecutive containers (#8016)

Browse Source 
* Fix: prevent nginx proxy read timeout from blocking AIO container startup

When AIO runs behind an nginx reverse proxy and a user clicks Start,
image pulls produce no streaming output for minutes at a time. nginx's
proxy_read_timeout fires, drops the upstream connection, and PHP then
aborts on the next write attempt (ignore_user_abort defaults to false),
leaving all containers after the first one never started.

Two fixes:
1. startStreamingResponse(): add ignore_user_abort(true) so PHP never
   terminates if the connection is already gone.
2. PullImage(): stream the Docker NDJSON pull response and write a
   "Pulling image" heartbeat at most once every 5 s, keeping the nginx
   connection alive.  Also surfaces Docker-level stream errors that the
   old buffered call silently ignored, guards against malformed
   newline-free responses with a 1 MB buffer limit, and unifies the
   duplicate catch-block retry logic.

* As heartbeat send a dot regularly

Rather than repeating the message, send a "magic" dot, which gets
appended to the previous line.

Previously the heartbeats weren't sent regulary because reading the data
into a buffer caused a lag.
