EXT-7165 FIXED panel outfit edit now observes all changes in COF (incl. wearables order changes)

- added observing changes in the COF (based on version changes of the COF category, COF's version is also updated when order of COF items is changed)
- got rid of outfit fetcher, cause the only used outfit is COF which is always in a fetched state
- minor cleanup
