Add database maintenance tooling

- Implement maintenance hooks (useMaintenanceTables, useVacuumTable, useAnalyzeTable, useReindexTable)
- Add DatabaseMaintenance page and UI for vacuum/analyze/reindex
- Wire new route / admin/database-maintenance and sidebar entry
- Remove DatabaseMaintenance icon usage on page and align with AdminLayout props
