fix(power): backport Power Button page collision fix to 7.3

[Eli Bosley (elibosley)]

Summary

Backport the Power Options page-name collision fix to the Unraid 7.3.3 line on top of the reviewed 7.3 Power Button implementation.

Why This Exists

The built-in Power Button page uses the same filename stem as the Dynamix System Buttons plugin. PageBuilder keys pages by basename, so the plugin can replace the built-in Power Button tab.

This is the 7.3.3 follow-up to DST-200. It depends on the configurable Power Button backport tracked by OS-644 and PR #2715.

Resolution

Rename the built-in PowerButton.page to PowerModeButton.page. The page content, visible title, and tab position remain 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 page 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

With Dynamix System Buttons installed, Settings > Power Options keeps both the Power Mode and Power Button tabs.

Implementation Summary

• Rename emhttp/plugins/dynamix/PowerButton.page to PowerModeButton.page.

Verification

• git diff --check
• Confirmed Menu="PowerMode:2" and Title="Power Button" remain unchanged.

Risk

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