feat: add hover tooltips to History Path column

Add title attributes to show full path information when hovering over entries
in the History page Path column. This helps users see truncated paths in full.

- Add title tooltip for file creation entries showing full file path
- Add title tooltip for rename entries showing "old_path → new_path" format
- Add title tooltip for other entries showing the path
- Maintains existing truncation styling with max-w-md class
