fix(power): backport Power Mode stylesheet fix to 7.3

[Eli Bosley (elibosley)]

Summary

Backport the Power Mode stylesheet filename fix to the Unraid 7.3.3 line on top of the reviewed 7.3 Power Options implementation.

Why This Exists

The Power Mode page is PowerModeCpu.page, but its stylesheet is PowerMode.css. PageBuilder loads stylesheets by basename, so the bare-metal rule that hides the virtualization warning does not load.

This is the 7.3.3 follow-up to OS-734. It depends on the configurable Power Button backport tracked by OS-644 and PR #2715.

Resolution

Rename PowerMode.css to PowerModeCpu.css. The stylesheet content remains unchanged.

Reviewer Considerations

• This branch starts from the reviewed PR feat(power): backport configurable power-button controls to 7.3 #2715 head e76c1e2 because the current 7.3 branch ref is before that merged PR.
• Because the current 7.3 ref is before PR feat(power): backport configurable power-button controls to 7.3 #2715, GitHub currently shows the prerequisite backport files in this PR diff. Those files are the required base for the fix, not new follow-up behavior. The diff reduces to the stylesheet rename after PR feat(power): backport configurable power-button controls to 7.3 #2715 is present on 7.3.
• The follow-up change itself is a file rename with no content changes.
• This PR intentionally contains no automated test. Tests were removed per request.

Behavior Changes

Bare-metal servers no longer show the virtualization warning in Settings > Power Options > Power Mode. Virtualized servers continue to show the warning when applicable.

Implementation Summary

• Rename emhttp/plugins/dynamix/sheets/PowerMode.css to PowerModeCpu.css.

Verification

• git diff --check
• Confirmed the div#vm rule retains display: none and margin-left: 35%.

Risk

Low. The stylesheet content is unchanged. Only the stylesheet basename changes.
