fix(swagger): correct type names in swagger docs

Rename icon-related types in swagger docs:
- homepage.FetchResult → iconfetch.Result
- homepage.IconMetaSearch → iconlist.IconMetaSearch
- homepage.IconSource → icons.Source
- Shorten enum varnames (IconSourceAbsolute → SourceAbsolute, etc.)
- Add x-nullable: true to rules arrays
