fix(version): use runtime config for version display

- Updated nuxt.config.ts to include version 0.3.1 and git hash in public runtime config
- Simplified /api/version endpoint to use runtime config instead of filesystem reads
- Updated Dockerfile to pass GIT_HASH and GIT_SHORT_HASH as build args and env vars
- This fixes the 'vunknown+unknown' issue in production by making version available at build time
