fix: revert production source maps to restore v1.67.0 memory baseline

CodeRabbit review addressed:
- Removed the env-var gating (simpler: just remove source maps entirely)
- CI health check now fails fast if container never becomes healthy

Changes vs origin/main:
- next.config.ts: remove productionBrowserSourceMaps and serverSourceMaps
  (they default to false, restoring pre-v1.68.0 behavior)
- Dockerfile: remove .map copy step and NODE_OPTIONS=--enable-source-maps
- CI: add memory-regression job (<700MB guardrail)

Closes #6123
