feat(v2.0.0): tsdb (#1162)

* feat: tsdb

* fix(ci): remove --parseGoList=false from swag init to fix dependency resolution

* fix(ci): fix swag init directory and temporary remove s390x support due to cgo issues

* fix(ci): fix swag init output directory to cmd/dashboard/docs

* fix(ci): set GOTOOLCHAIN=auto for gosec

* feat: add system storage maintenance for SQLite and TSDB

* shit

* feat: add s390x support and improve service monitoring

* ci: upgrade goreleaser-cross image to v1.25

* ci: add libzstd-dev:s390x for cross-compilation

* ci: build libzstd for s390x from source

* ci: add libzstd_linux_s390x.go for gozstd linking

* ci: use vendor mode for s390x gozstd build

* ci: clone zstd source for s390x build

* refactor(tsdb): rename MaxDiskUsageGB to MinFreeDiskSpaceGB and optimize queries

- Rename config to accurately reflect VictoriaMetrics behavior: minimum free disk space threshold
- Add QueryServiceHistoryByServerID for batch query optimization
- Fix hasStatus to avoid false status counting when only delay data exists
- Fix service aggregation boundary: use successCount*2 >= count
- Fix serviceID parsing with strconv.ParseUint error handling
- Add TagFiltersCacheSize for better query performance

* feat(api): add server metrics endpoint and simplify service history response

- Add /server/:id/metrics API for querying TSDB server metrics
- Simplify getServiceHistory by removing redundant data conversion
- Change AvgDelay type from float32 to float64
- Remove generated swagger docs (to be regenerated)
- Update TSDB query, writer and tests

* chore: 临时禁用不支持前端

* ci: cache zstd build for s390x to speed up CI

* fix(tsdb): fix race conditions, data correctness and optimize performance

- Fix TOCTOU race between IsClosed() and write/query by holding RLock
- Fix delay=0 excluded from stats by using hasDelay flag instead of value > 0
- Fix fmt.Sscanf -> strconv.ParseUint for server_id parsing with error logging
- Fix buffer unbounded growth by flushing inside lock when over maxSize
- Split makeMetricRow into makeServerMetricRow/makeServiceMetricRow
- Extract InitGlobalSettings() from Open() for VictoriaMetrics globals
- Remove redundant instance/GetInstance/SetInstance singleton
- Add error logging for silently skipped block decode errors
- Optimize WriteBatch* to build all rows in single write call
- Optimize downsample to use linear scan instead of map for sorted data
- Optimize query slice reuse across block iterations

* 服务添加DisplayIndex (#1166)

* 服务添加DisplayIndex

* 根据ai建议修改

* fix(tsdb): restore SQLite fallback and monthly status reload on restart

- Restore ServiceHistory model and SQLite write fallback when TSDB is disabled
- Reload monthlyStatus (30-day) and serviceStatusToday from TSDB/SQLite on startup
- Add SQLite fallback query for /service/:id/history and /server/:id/service
- Remove breaking GET /service/:id endpoint, keep /service/:id/history only
- Add QueryServiceDailyStats to TSDB for per-day aggregation
- Add tests for monthly status and today stats loading from both TSDB and SQLite
- Migrate ServiceHistory table only when TSDB is disabled

* ci: exclude false-positive gosec rules G117, G703, G704

* feat(api): expose tsdb_enabled in setting response

* ci: restore G115 exclusion accidentally dropped in previous commit

* fix: update version numbers for OfficialAdmin and Official templates

* chore: upgrade frontend

* chore: upgrade frontend
