refactor: Improve channel status update logic and clean up code

- Simplified conditional checks in UpdateChannelStatusById function in channel.go to enhance readability.
- Commented out unused image number check in relay-gemini.go for clarity.
- Updated JSON field in en.json for currency consistency, changing "元" from "RMB/CNY" to "CNY" and added a space in "实付金额：" for formatting.
