[ivaylo-matov]

Purpose

This PR addresses DYN-9357

It improves clarity in the Search tab so users can easily see which version of a package is currently installed:

• the version dropdown now defaults to the installed version.
• the installed version in the dropdown is labeled with an “(installed)” suffix.
• a badge is shown when a newer version of the package is available.
• the Install button now:
  • displays “Update” when a different version is available.
  • displays “Uninstall” when the installed version is selected.

Changes in code:

• install state tracking in the search element view model (installed version, selected version, update availability).
• InstallActionText / InstallActionCommand so the button label and action change based on state.
• fallback “Installed” state when uninstall isn’t possible.
• added a null guard when downloading a selected version to avoid crashes.
