Fix: read files from symlink directory in background selector menu

[tushar-chauhan]

This PR adds support for listing images from a symlink directory, having same name as the theme name within the ~/.config/omarchy/backgrounds directory.

Scenario:
If we have a common wallpapers directory at ~/Pictures/Wallpapers.
And we create symlink for this directory in ~/.config/omarchy/backgrounds with correct theme name convention like:

• ln -s ~/Pictures/Wallpapers ~/.config/omarchy/backgrounds/lumon, OR,
• ln -s ~/Pictures/Wallpapers ~/.config/omarchy/backgrounds/tokyo-night

The omarchy background selector menu does not show the images from the symlinked directory.

The update in this PR adds support for:

• Listing the default theme backgrounds, and

  • 

• Images from the symlink directory

  •

Pull request overview

This PR updates the Omarchy background selector provider to correctly list images when the theme’s user backgrounds directory (~/.config/omarchy/backgrounds/<theme>) is a symlink to another directory (e.g., ~/Pictures/Wallpapers).

Changes:

• Add a helper to resolve a theme backgrounds path to its symlink target via realpath.
• Use the resolved path (when available) when building the list of directories scanned for images.
