✨ feat(desktop): unify canary with stable app name/icon, add channel tag in About (#12881)

- Use same app name (LobeHub) and icon as stable for canary builds
- Add build channel tag in Settings > About for non-stable channels (Canary, Nightly, Beta)
- Add getBuildChannel IPC to expose build-time channel for display
