web-app-chess: build/runtime hardening & feature enablement

Browse Source 
Build: use Yarn 4 via Corepack; immutable install with inline builds.

Runtime: enable Corepack as user 'node', use project-local cache (/app/.yarn/cache), add curl; fix ownership.

Entrypoint: generate keys in correct dir; run 'yarn install --immutable --inline-builds' before migrations; wait for Postgres.

Config: enable matomo/css/desktop; notify 'docker compose build' on entrypoint changes.

Docs: rename README title to 'Chess'.
