Add partition management integration to the smart ops system:
- Backend: Add GetUsageLogsPartitionStatus endpoint in OpsHandler
- Backend: Add partition query methods in OpsRepository
- Backend: Add UsageLogsPartitionStatus type in OpsService
- Frontend: Add OpsPartitionStatusCard component
- Frontend: Add partition status display in OpsDashboard
- i18n: Add Chinese and English translations
The partition status card shows:
- Whether usage_logs is partitioned
- Current row count vs threshold (100K)
- Partition count (if partitioned)
- Warning message when partitioning is recommended
This allows administrators to monitor partition status directly
from the ops dashboard without checking server logs.
