Make _media_relative_path() honor its Windows-path contract.
When a Windows-created archive is served on POSIX, Path(file_path).is_absolute() returns False for C:\media\chat\photo.jpg. The function then passes C:/media/chat/photo.jpg as a relative path, so _resolve_media_file() searches for the wrong path below _media_root and can return 404.
Use path-flavor-aware conversion to map Windows absolute paths to the configured media root. Add regression tests for Windows-formatted paths on POSIX and Windows.

Summary
Fix Windows media path normalization
This fixes thumbnail requests for media entries whose database file_path contains an absolute Windows path. The fix also normalizes Windows path separators and rejects paths outside the configured media root or containing traversal components.
No changes to the media URL/API format are required.
