feat(statistic): T9-T12 dashboard 7 RPCs (Provider + Materializer + Service + Cache)

- StatisticInternalProvider: TrackEvent/BatchTrackEvent
- StatisticCombinedProvider: all 9 RPCs (7 dashboard + 2 event) on single service
- materializer: 4 MV REFRESH CONCURRENTLY + pg_try_advisory_lock + refresh_log
- dashboard_repo: 7 aggregation SQLs (week_rank / 7d curve / top5 / level dist / upgrade progress)
- dashboard_service: 7 RPCs with Redis 5min TTL + cache miss protection (1min empty)
- Cache wrapper: JSON serialize + format dash:{rpc}:{starID}:{userID}
- main.go: integrated workers + Dubbo triple server :20009
- cross-service userService.GetFanProfile (for crystal_balance)
- client/user_rpc_client.go
