[FEAT/UI]: Implement Quota Governance Dashboard View Mapping Tenant Isolation Capability Overrides

Problem

Enterprise administrators scaling multi-agent environments require a single visual ledger to govern active access structures and check per-tenant rate-limiting token bucket capacities [1.5].

Proposed Solution

Scaffold an isolation monitoring matrix screen panel under ui/app/dashboard/governance/:

1. The Blast Radius Containment Table: Render detailed rows tracking multi-tenant indicators: Workspace ID, Active Workflow Channels, Token Bucket Flow Rates, and Threat Score indices [1.1, 1.5].
2. Interactive Threshold Slivers: Embed clean configuration slider controls to programmatically adjust tenant thread allocations directly through backend network gateway interfaces [1.5].

Use Case

Fulfills the high-density compliance isolation safety metrics required by institutional corporate platform purchasers [1.5].

Start by inspecting the existing dashboard structure and the ui/app/dashboard/governance/ entry point. Define how the isolation monitoring matrix should represent Workspace ID, workflow channels, token bucket flow rates, and threat scores, then trace the backend network gateway interface for threshold updates. Done means the governance panel renders the listed tenant indicators and provides the requested allocation controls.
