Reduce duplicate scan terminal decision copy and chrome

Removed the scan KPI bar, trimmed redundant decision-card content, and shortened the primary reason text so the city analysis cards read like concise signals instead of repeating the same state across sections.

Constraint: Keep existing city decision logic and data flow unchanged while simplifying the UI
Rejected: Rework the full card layout or mobile card flow | larger surface area than requested
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep hero, decision band, and market line responsibilities separate to avoid duplicate copy returning
Tested: frontend npm run build
Not-tested: Manual visual QA in browser across desktop/mobile breakpoints
