fix(docker): build assets on start when the manifest is missing

With the Vite dev server off by default, a fresh checkout had no public/build
(gitignored, and the image does not build it), so every @vite page failed with
ViteManifestNotFoundException. The entrypoint now builds once when the manifest
is absent, non-fatally — a broken build must not wedge the container into a
restart loop where the logs are unreachable.

Proven by deleting public/build and restarting: assets rebuilt automatically,
page 200.
