chore(scripts): realistic ClickHouse seed data and quieter output

[macko911]

Summary

• Add gradual connection growth (per-integration 10–20% over the seed window), weekend traffic dips, and day-to-day jitter for flow metrics (runs, records, function time, proxy, etc.)
• Quiet default npm run seed:clickhouse output (success line only); --verbose for per-env progress and library logs
• Demote per-migration ClickHouse logs to debug; one summary info line when migrations run

Test plan

• npm run seed:clickhouse — single-line success output
• npm run seed:clickhouse -- --verbose — full progress + migration logs
• Billing dashboard shows upward connection trend and weekend dips on flow metrics

• In scripts/seed-clickhouse.ts, the dayScale < 0.45 skip threshold appears unreachable for normal --days inputs, so the “quietest-day” seeding behavior likely never runs and seeded traffic patterns may be less realistic than intended; adjust the threshold or scaling math (or add a small test/assertion around expected activation) before merging to de-risk future confusion.

<violation number="1" location="scripts/seed-clickhouse.ts:273">
P3: The `dayScale < 0.45` threshold for connection skipping is unreachable with the script's default `--days 30` (min ~0.57) and even `--days 60` (min ~0.48). The intended quietest-day behavior only activates with unusually long seed windows (90+ days). Either lower the threshold to match the actual dayScale range (~0.48–0.57 for practical windows) or remove the branch if the behavior isn't needed.</violation>
