fix(docker): revert runtime base image to python:3.13-slim

#1290 bumped the runtime stage to python:3.14-slim. gensim is a base
(non-extras-gated) dependency and publishes no cp314 wheel on PyPI, so
pip falls back to building it from source, which needs a C compiler
this slim image doesn't carry:

  error: [Errno 2] No such file or directory: 'gcc'

This has broken the Docker build (and Container Security Scan) on
every push to main since #1290 merged. Confirmed via
`pip index versions gensim` / the PyPI files listing that gensim 4.4.0
ships cp313 wheels but no cp314 ones; the earlier lockfile fix in
#1290 only validated that `uv pip compile` could *resolve* dependencies
for 3.14, which reads sdist metadata and doesn't need a compiler --
it doesn't validate that `pip install` can actually *build* them,
which is what fails here.

Reverts to the exact base image digest that was building successfully
before #1290 and regenerates explorer-extra-py313.txt against today's
PyPI state. Once gensim (and anything else pulled in transitively)
ships cp314 wheels, the 3.14 bump can be retried.
