Claude dashboard drill-downs and TTL clarity
- fixed session turn breakdowns to key off stable session identity instead of fragile slugs
- added TTL mix visibility (
1hvs5m) in session tables and per-turn drill-downs - added pacing metrics for time between assistant API calls
- added hover explanations for dashboard columns like
Cache,TTL,Pacing,Cache R, andCache W - added served-dashboard on-demand loading for older session drill-downs while keeping the static dashboard bounded for speed
- fixed the served
/api/session-turnsresponse path
