Add ability to rotate all wallpapers

[gitfudge0]

TL;DR

Added a "rotate all wallpapers" mode that allows the rotation service to cycle through all discovered wallpapers instead of just manually selected ones, while preserving the manual rotation list.

What changed?

• Added rotate_all_wallpapers boolean field to the configuration with toggle functionality
• Modified the rotation service to use all wallpapers when this mode is enabled, falling back to the manual selection when disabled
• Updated the rotation popup (R key) to include a toggle option for switching between "selected wallpapers" and "all wallpapers" modes
• Enhanced the rotation section UI to display an informational message when in "all wallpapers" mode
• Updated the rotation service status display to show the current mode and entry count
• Added automatic service restart when configuration changes affect rotation behavior
• Removed the opencode GitHub workflow
• Bumped version from 0.3.2 to 0.4.0

How to test?

1. Open Walt and press R to access the rotation popup
2. Select "Rotate all wallpapers" to enable the new mode
3. Verify the rotation section shows the informational message
4. Check that walt rotation status displays "Mode: all wallpapers" and "Entries: all wallpapers"
5. Toggle back to "Use selected wallpapers" and confirm it returns to manual selection mode
6. Test that the background service respects the mode setting when rotating wallpapers

Why make this change?

This change provides users with more flexibility in how wallpaper rotation works. Instead of requiring manual curation of a rotation list, users can now choose to rotate through their entire wallpaper collection automatically while still preserving their manually selected favorites for when they want more control.
