Refactor FileTreeModel to batch item additions in a single model reset cycle instead of resetting per item. For archives with ~5,400 files, this reduces model resets from 5,400 to 1. - Extract _addItemInternal() for core add logic without signals - Update addItems() to wrap all additions in single begin/endResetModel - Update parse_json_lines() in extract_dialog.py to use batch API - Update parse_diff_json() and parse_diff_lines() in diff_result.py
Add isomtime field to test data default dictionary so tests work regardless of borg_compat.version state. The code uses either mtime or isomtime depending on borg version, so providing both ensures tests pass when run in isolation or alongside other tests.
