fix: use build output directory for backup test temp root to avoid low free-space failures on Windows CI runners

2026-07-21T06:54:23Z

BackupServiceTests rooted its temp directory under Path.GetTempPath(), which on GitHub-hosted windows-latest runners resolves to the constrained system C: drive. BackupService.CreateBackupAsync requires 5GiB free at the backup path before starting, and the C: drive's free temp space can dip below that, failing CreateBackupAsync_WithCorruptKeyframeDataRow_SkipsRowAndCompletesBackup even though the fix itself is correct. Rooting the test directory under AppContext.BaseDirectory keeps it on the same (much larger) drive as the repo checkout on all platforms, without touching the real BackupService free-space check.

Skip corrupt KeyframeData rows during full system backup

2026-07-17T14:44:25Z

A single row with malformed KeyframeTicks JSON (e.g. a truncated array from an interrupted write) currently aborts the entire backup, because the try/catch in BackupService.CreateBackupAsync only wraps serialization of an already-materialized entity, not the enumeration itself. EF Core throws JsonReaderException from MoveNextAsync() while materializing the corrupt row, which propagates past that catch block. Switch to manual enumerator iteration so MoveNextAsync() failures can be caught per-row, logged as a warning identifying the affected table, and skipped, allowing the remaining rows and the rest of the backup to complete.
