feat: add OpenTelemetry device log capture pipeline

- ClickHouse `logs` table (migration 13) with OTel columns, bloom filter indices
- Zod validation schema for log payloads (severity, body, attributes, trace context)
- Redis-backed LogBuffer with micro-batching into ClickHouse
- POST /logs API endpoint with client auth, geo + UA enrichment
- BullMQ logs queue + worker job
- cron flushLogs every 10s wired into existing cron system
- SDK captureLog(severity, body, properties) with client-side batching
