src/web/pages/flow.ts drops the unused live and readQueues imports #39

Closes forge tracker issue #2171 (https://forge-trevato-apps.open-platform.sh/trevato/forge/issues/2171). Pillar (2) Cut the noise.

After #2139 the flow page reads duplicates through systemFor and the queue through queuesFor, so live (from system/live.ts) and the value readQueues (from flow/queue.ts) were imported and never used. tsc doesn't flag them because noUnusedLocals is off. This drops the live import and keeps only import type { QueueRow }. Both modules still load through system/telemetry.ts, so nothing changes at import time. No behaviour change.

Tests:

• bun scripts/gate.ts: exit 0
• ./node_modules/typescript/bin/tsc --noEmit: clean
• bun test --timeout 60000 on flow-pipeline, flow-throughput, flow-stage, flow-card, merge-queue, crew-held, system-telemetry and check-list: 79 pass, 0 fail across 8 files

The full gate wasn't run locally.
