fix(miniapp): default market submissions to client version - #1922

Summary

• default manual MiniApp market submissions to the running Tauri client's package version
• default Agent PublishMiniApp submissions to the current BitFun workspace build version
• preserve an explicitly entered minimum BitFun version across refreshes
• remove the production 0.1.0 defaults from both submission paths and add focused coverage

This changes the default minimum BitFun version only. It does not change the market release number and does not prevent users from entering an older compatible minimum manually.
