Sync loop root-cause fixes (three independent bugs): 1. Folder change clears stale file states (AddPairViewModel): when localPath or remotePath changes on an existing pair, all SyncFileStateEntity records are wiped. Previously those stale records caused every sync to attempt DELETE_REMOTE on the old folder's files and to treat all new-folder files as changed — causing both the "deleting 32 files" loop and rewrites on every run. 2. Download stores null localModifiedAt (SyncEngine): SAF document cursors can return a stale mtime immediately after a write. Storing null forces the SKIP reconciliation pass on the next sync to read the actual walkFiles cursor value, breaking the download->changed-> download loop caused by mtime inconsistency. 3. Second-precision mtime comparison (syncDecide): WebDAV RFC-1123 has 1-second precision; FAT32 has 2-second precision. Comparing at millisecond level caused phantom "changed" detections after syncing to/from these systems. Now uses epochSecond for both local and remote.
