Switch from broken StdioClientTransport (child process) to
SSEClientTransport (HTTP to sidecar containers via supergateway).
Both sidecars share rspace-files volume so generated CAD files
(STEP, STL, Gerber, SVG) are directly servable without copying.

The Scribus --python-script flag requires GUI initialization which
blocks in headless environments. Instead, run the runner as a separate
supervisor-managed Python process (always-on socket server). The bridge
server now simply verifies the socket exists rather than launching
Scribus.

Scribus 1.5 --no-gui mode doesn't execute --python-script properly.
Remove the flag and let Scribus use the Xvfb display, which also
enables the runner to create the bridge socket.

The bridge's /start endpoint was returning "already running" even when
the runner script had crashed (socket gone). Now kills zombie Scribus
and restarts. Agent route also verifies runner connectivity after start.
