DashboardService was constructing 'today in Beijing' bounds with a +08:00 offset, which Npgsql rejects when binding to a timestamp with time zone column. Added .ToUniversalTime() to normalize to UTC (same instant, offset 0), matching the existing pattern in SessionAnalyticsService.GetUtcWindow.
Introduce a process-wide DatabaseCircuitBreaker that fails fast when Postgres is unavailable (e.g. disk full) instead of letting every request burn doomed EF Core retries. CircuitAwareExecutionStrategy derives from NpgsqlRetryingExecutionStrategy and records success/failure around the public Execute/ExecuteAsync seams; background workers skip work and back off while the circuit is open; the exception middleware maps an open circuit (and other DB outages) to 503. Adds /health (liveness) and /health/ready (readiness, reporting circuit state), plus unit tests for the open/half-open transitions and non-transient SQLSTATE detection.

Add a segment-level cleanup alongside the existing session-level one. DeleteMissingFileTasksAsync scans all non-active record tasks, keeps those whose video file no longer exists on disk, and deletes them individually via DeleteTasksAsync (which also drops any session left empty). Exposed as POST /record-tasks/delete-missing-files and a new "清理无文件分片" action in the record tasks view.

- CanStartNewRecording now purely based on Tier==Green (was HasEnoughSpace||Green)
- PollingBackgroundService now uses ShouldPauseActive instead of MB-based CheckShouldPause
- Both pause and start checks consolidated into single guardCheck call
- Old MB pause/resume thresholds still work as secondary safety via hasEnoughSpace

Add StorageGreenThresholdPercent (default 30%) and StorageRedThresholdPercent
(default 10%) to both SystemSettingsDto and the settings UI.
StorageGuardService now reads thresholds from settings instead of hardcoding.

DbContext is not thread-safe. Task.WhenAll caused concurrent access
within the same scoped DbContext, throwing 'A second operation was
started on this context instance' errors on slower machines.
