Summary

Add fixed Y-axis (0-220M) so the 200M autovacuum threshold is always visible
Add dashed threshold lines at 150M (yellow warning) and 200M (red danger)
Update title to clarify the threshold

Context

The raw XID age naturally trends upward between vacuum freezes, which looked alarming without context. Current values (~143K-216K) are at 0.1% of the threshold - completely healthy.

Deployment and Testing

Sync grafana-config app to feature branch
Verify threshold lines appear on PostgreSQL dashboard

Fix XID Age graph to show threshold context 377efeb22c

- Add fixed Y-axis (0-220M) so the autovacuum threshold is always visible
- Add dashed threshold lines at 150M (yellow) and 200M (red)
- Update title to mention the 200M threshold

The raw XID age will always trend upward between vacuum freezes,
which looked alarming without context. Now the graph shows how
far the value is from the autovacuum_freeze_max_age threshold.
