feat(display): add display configuration management

[maxinglo]

Pull Request

Motivation

This PR adds a unified display configuration workflow to Noctalia so users can manage monitor topology and per-output settings directly from the Display panel, with safer recovery behavior.

It introduces:

• A dedicated monitor management UI (MonitorSubTab) for layout drag/snap and per-output controls.
• A new display service layer (DisplayService) to normalize topology state, queue apply commands, and handle confirm/revert.
• Compositor backend integration for Hyprland and niri, with wlroots/readonly fallback behavior.
• EDID read/parse/copy flow for monitor diagnostics.
• New i18n strings in en.json and zh-CN.json.

Except this one and missing translation keys. this is great so far.

I have a suggestion: About merging Brightness + Monitor tabs

[maxinglo]

Brightness settings are merged into monitor tab now.

That was fast

Added persistence by writing to the compositor's config files to fix some compositor settings reverting to defaults on reboot. To be honest, the current approach feels a bit clunky, and I’m looking for a more elegant way to handle this. If you have any better ideas, please let me know.

Before that there are a few syntax issue(s): 4

111: Unclosed bracket

Unterminated regex:

789: /VendorName\s+"([^"]+)"/i
804: /EDID(?:\s+Version)?\s*:?\s*([0-9]+.[0-9]+)/i
819: text.match(/Made\s+in:\s+week\s+([0-9]+)\s+of\s+([0-9]{4})/i);

'name=$(basename "$dev" | cut -d"-" -f2-);'

I think this one is fine.

[turannul]

'name=$(basename "$dev" | cut -d"-" -f2-);'

I think this one is fine.

probably, its not the wrong one but vscode still shows unmatched/unclosed here

in order to simplify using roughly pattern like this one?
var script = [] return _joinShell(script)

I think it's the problem of that qml vscode plugin. And it will still shows unmatched/unclosed after rewrite.

Indeed vscode issue atleast could be, weird part is im not using QML lsp.
