fix(opencode): fix add/remove provider flow and toast messages

- Create separate removeFromLiveConfig API for additive mode apps
  (remove only removes from live config, not database)
- Fix useSwitchProviderMutation to invalidate opencodeLiveProviderIds
  cache so button state updates correctly after add operation
- Show appropriate toast messages:
  - Add: "已添加到配置" / "Added to config"
  - Remove: "已从配置移除" / "Removed from config"
- Add i18n texts for addToConfigSuccess and removeFromConfigSuccess
