Employee detail rail shows manager as raw ID instead of resolved name #150

Description

The employee detail panel's Details section renders the manager as ID: <manager_id> (e.g. ID: fixture-emp-priya) instead of the manager's resolved full name, even when the manager exists in the loaded employee list. Observed 2026-07-14 during People Map T10 verification with dev fixtures.

Current State

EmployeeDetail.tsx passes managerName={manager?.full_name} to DetailsSection; the fallback renders the raw ID. The manager lookup evidently misses even when the manager row exists (fixture-emp-priya was present and active). Likely the lookup searches a filtered/paginated list rather than fetching by ID.

Suggested Fix

• Trace how manager is resolved in EmployeeDetail.tsx (list lookup vs get_employee fetch)
• Resolve by ID via the backend command when not present in the loaded list
• Fall back to the raw ID only when the reference is genuinely dangling (mirror the backend's skip-not-fatal behavior in people_map/context.rs)

Verification

• npm test passes (add a case: manager resolved when not in the visible list)
• npx tsc --noEmit clean
• Dev app: fixture-emp-maya shows "Priya Raman" as manager, not the ID
