fix(desktop-ui): resolve linting and typecheck errors (#7271)

Fixes linting configuration and type errors in apps/desktop-ui.

## Changes
- Updated `eslint.config.ts` to use absolute path for `.oxlintrc.json`
resolution.
- Fixed `import-x` errors in `InstallFooter.vue`, `refUtil.ts`, and
`DesktopDialogView.vue`.
- Fixed i18n raw text error in `NotSupportedView.vue` via
eslint-disable.
- Fixed type inference issue in `i18n.ts` allowing dynamic locale
switching.
