fix(docker): honor USE_DDTRACE in the componentized gateway and backend images (#35490)
The componentized images exec uvicorn directly, so ddtrace-run never wraps the
interpreter. USE_DDTRACE is not inert there; the proxy lifespan still runs
patch_all and litellm's own manual spans still emit. What never gets installed
is ddtrace's ASGI TraceMiddleware: starlette builds its middleware stack lazily
on the first __call__, which is the lifespan scope, so patching from inside the
lifespan body is already too late and no root request span is ever created.

Route both entrypoints through a shared docker/component_entrypoint.sh that
mirrors the monolith's prod_entrypoint.sh contract, including the
DD_TRACE_OPENAI_ENABLED=False export that keeps ddtrace's openai integration
from double-reporting calls litellm instruments itself.
