Add Sentry source maps and release tracking

- @sentry/vite-plugin uploads source maps during Docker build
- Release tagged with git SHA (SENTRY_RELEASE) on both client and server
- Environment set to production/development for filtering
- CD passes SENTRY_AUTH_TOKEN + SENTRY_RELEASE as Docker build args
- docker-compose passes SENTRY_RELEASE to runtime containers
