gsxdsm b9c5df04af FN-8791: prevent NUL-containing chat checkpoints from crashing

Prevent malformed tool output from breaking chat checkpoint persistence.

- Sanitize NUL characters at chat JSONB persistence boundaries without mutating clean values.
- Observe rejected best-effort checkpoint writes so streaming sessions do not emit unhandled rejections.
- Add PostgreSQL, dashboard, and sanitizer regression coverage with operator-facing release notes.
