v1.1.3 — Analytics workspace filter + Cache/Models/Latency tabs

What's new

Bug Fixes

• Fix analytics workspace filter not applying — selecting a specific workspace in the Analytics sidebar now correctly filters all metrics (sessions, tokens, cost, charts) to that workspace only. Today stats used for sidebar activity badges remain unfiltered.
• Fix Cache, Models, and Latency analytics tabs showing empty — all three tabs now compute and display real data from session summaries: cache hit ratio and cost savings, per-model cost/turn efficiency, daily model cost breakdown, and turn latency distribution histogram with p50/p95/p99 percentiles.
