perf: replace O(N·chunks) listForRadar read path with O(N·agents) metrics lookup

Browse Source 
listForRadar previously called findByAgentIds() and JSON-parsed every chunk to
compute questionsCount, subagentsCount, and compactionsCount. Switch to
findMetricsByAgentIds() which reads the pre-computed agent_metrics table,
eliminating the chunk scan and per-row JSON.parse entirely.

Add two new test cases: agent with no metrics row returns zero counts, and
listForRadar response rows never carry chunk content.
