Summary

Fixes the file explorer opening the wrong directory on Linux when using OpenFileManager().

Root Cause

The pathToURI function was using url.PathEscape which incorrectly escapes forward slashes:

/home/angaz -> file://%2Fhome%2Fangaz (broken)

File managers couldn't parse these malformed URIs correctly, causing them to open the wrong directory (often a parent directory like /home instead of /home/angaz).

Fix

Changed to use url.URL struct which properly constructs file URIs:

/home/angaz -> file:///home/angaz (correct)

Spaces and other special characters are still properly escaped (e.g., My Documents → My%20Documents).

Test plan

• Test OpenFileManager("/home/username", true) opens the correct directory
• Test paths with spaces work correctly
• Test with different file managers (Nautilus, Dolphin, Thunar, etc.)

Fixes #4397
