Improve compatibility with compose plugin and third party containers (like nextcloud-aio)

[Joly0]

This PR focuses on improving the usability and overal visuals of folders when containers in folders are managed by compose plugin or are third party (like for nextcloud-aio managed containers).

Comparision: Before:

After:

As seen on the screenshots, the immich folder is no longer showing an update available, and instead shows "compose" with the icon thats used for the compose containers. Also for testing i added the webtop container to the nextcloud folder to show that updates are still correctly shown for compose folders with a single dockerman container in it that has an update (in that case webtop). For mixed folders, the label "mixed" is used, which correctly switches to "apply update" as seen in the "web services" folder which contains dockerman and compose containers. Everything is untouched.

Should fix https://github.com/VladoPortos/folder.view2/issues/13 though maybe the text could be white aswell, instead of green, but thats up for a debate.
