feat(ui/conf): add preferRemoteConf option (#1000)

Add `preferRemoteConf` option (disabled by default).

Local config now takes priority, addressing the issue where remote config previously overrode local settings. (Closes #1000)

Updated config merging logic in `mount.ts`.

Deprecated `useBackendConf` in favor of `preferRemoteConf`.

(The prerequisite PR is #1007)

BREAKING CHANGE: The UI client now prioritizes local config in the latest version, whereas previously, the remote config would override it.
