Fix sanitize_map_name to match Windows filename rules

[danmaps]

Summary\n- Make sanitize_map_name() replace the full Windows-invalid filename set (including ASCII control chars) and collapse whitespace.\n- Add pytest coverage for invalid chars, control chars, truncation, and fallback behavior.\n\n## Why\nProExporter writes map images using sanitized names. If the CLI sanitization is less strict than Windows rules (or the C# logic), it can lead to mismatches when looking up map image filenames.\n\n## Testing\n- python -m pytest\n
