Migrate `sw-color-badge` to `mt-color-badge` in the Administration

Sub-issue of #15461.

### Scope

Replace all remaining `` usages in the Administration with ``.

Usage at the time of writing: **25 occurrences in 12 files**

```bash
grep -rE '/]|$)' src/Administration/Resources/app/administration/src
```

### Acceptance criteria

- All in-scope `` tags are replaced by ``.
- No new usages of `sw-color-badge` are introduced.
- Behaviour parity is maintained for props, emitted events and slot content.
- Unit/E2E tests are updated only where selectors or DOM structure changed.
- AC validation is based on component tags (`sw-color-badge` -> `mt-color-badge`), not on
internal Meteor DOM classes (e.g. `.mt-color-badge`).
- Wrapper or deprecated fallback usage is not required for this component.

Start in src/Administration/Resources/app/administration/src and run the issue's grep command to locate all 25 sw-color-badge usages across 12 files. Replace the component tags while preserving props, emitted events, and slot content; inspect any affected unit or E2E selectors where DOM structure changes. Done means no in-scope sw-color-badge tags remain and no new usages are introduced.
