Add office operations center panel

[iamlukethedev]

Summary

• Add an Ops tab to the HQ sidebar.
• Add an operations center panel with fleet counts, prioritized agent roster, recent run outcomes, and recent activity feed.
• Reuse existing AgentState, runLog, feedEvents, and run counts instead of introducing a new store.
• Open HQ to Ops by default so multi-agent visibility is the first sidebar view.
• Add focused component coverage for summary counts and agent selection.

Testing

• npm run test -- --run tests/unit/operationsCenterPanel.test.ts tests/unit/stateAnimationMappingsEditor.test.tsx tests/unit/studioSettings.test.ts tests/unit/officeEventTriggers.test.ts
• npm run typecheck
• npm run smoke:dev-server
• Browser walkthrough opened /office, opened HQ, and verified Operations Center/Fleet roster/Recent runs/Activity stream with zero browser console errors. Note: the walkthrough also shows an existing canvas white-background issue when HQ opens in this dev/browser session; the Ops panel itself renders and functions.
