[BUG] wallpaper_depth plugin fails if wallpaper is a symlink

[trinistr]

Submission checklist

• I have searched existing issues and confirmed this is not a duplicate.
• I am using the latest available version of Noctalia.

Bug description

wallpaper_depth plugin fails to set generated mask if wallpaper is set to a symlink, as one side of path comparison (completedJob.wallpaperPath) resolves the symlink in service.luau:217, leading to comparison returning false.

Steps to reproduce

1. In Noctalia's wallpaper settings set wallpaper to a symlink.
2. Install plugin.
3. Look at output in plugin's panel.

Expected behavior

Mask is generated and set successfully.

Actual behavior

Mask is generated successfully, but is not set, because plugin believes the wallpaper is different.

Logs / error output

Only visible output is ["service.invalid_result"](https://github.com/noctalia-dev/official-plugins/blob/8cb833c3e2502f57e49d34fa64386b4d66794b77/wallpaper_depth/service.luau#L222) error's translation.

Additional context

• Commenting out path comparison allows plugin to work correctly.
• service.luau needs to be saved/reloaded twice to actually work.
