Desk issues on version-16: icons not updating, old icons coming back, and folder/edit mode problems

Hi, I worked on a fix for several Desk issues on version-16, but I’m not able to open a PR directly from my account, so I’m sharing the branch here in case a maintainer can help submit it upstream.

Branch: https://github.com/Akshay-Arijentek/frappe/tree/fix/desk-icon-layout-shortcuts

Commit: 77db912026

Main issues fixed:

• adding the same item to the desktop again could fail with an error
• some desktop icons were not updating properly after changes
• deleted icons could still show up again after refresh
• shortcut icons like POS / Employee Portal could disappear or not load correctly
• the “Add to Desktop” success message was not showing
• Desk could break if icon color/style data was incomplete
• in edit mode, right-click menus could pile up and make the page messy
• creating folders was awkward and often ended up with Untitled names
• adding items to folders and saving the layout was not always stable

I tested this locally on version-16, and the branch is already pushed and ready.

If possible, could a maintainer or contributor help open a PR from this branch? @sokumon
