fix(infra): include shared-logger in mana-ai + mana-auth Dockerfile installers

shared-hono declares @mana/shared-logger as a workspace dep. Without
that package in the installer stage, Bun fails at runtime with ENOENT
reading /app/packages/shared-hono/node_modules/@mana/shared-logger.
Caught when mana-ai crash-looped on first boot.
