fix(dto): align daily_login_bonus DTOs with prod wire shape

- numeric fields ship as quoted strings (campaign_id, img, effect_id,
  reward_type, reward_detail_id, reward_number)
- DailyLoginBonus.Campaign is a List<>, not a single object
- LoginBonusCampaign.Img replaces Image (string, asset-key)
- add IsOneDayMultiRewards (SpecialData-only on client, byte-faithful)
