feat(workspace,jobs): emit sync_aborted_on_restart audit + enrich worktree.pruned metadata

- workspace.ResetStuckSyncStatuses now returns affected IDs so app.New can record one workspace.sync_aborted_on_restart audit per reset row
- worktree_prune audit metadata gains workspace_id and path alongside existing branch
- updated fakeRepo + integration test for new ResetStuckSyncStatuses signature
- add TestWorktreePrune_AuditMetadataContainsWorkspaceIDAndPath
