fix(api): align API layer with backend response formats

- wallet: parse {balance: string} response
- favorites: addFavorite returns void (EmptyResp)
- services: handle paginated response from listServicesByPlayer
- files: use query param ?key= instead of path param /:id
- search: remove unsupported selectedGames/minRating params
