fix: resolve 48 lint errors in test files

- Remove whitespace from 22 blank lines (W293)
- Remove 6 unused imports (F401): os, Mock, MagicMock, Path
- Add missing imports for 12 test functions (F821): sanitize_filename, extract_remote_path, MagicMock
- Fix 1 unsorted import block (I001)

All ruff checks now pass successfully.
