fix: align song text in panel on song change

[Nicolas-Gth]

PR #267 introduced a circular width dependency in the panel text layout: ScrollingText was changed from explicit width + Layout.preferredWidth to Layout.fillWidth: true, which meant the text container's width was assigned by the parent layout rather than computed from the text content. On song change, the centering position was calculated from the stale (previous song) width and never updated.

Here's my fix:

Instead of resizing the text box to fit the content and then centering it, the text box now always takes up all available space and the text is centered visually inside it.

Also fixes a binding loop on animationRunning/text in ScrollingText.qml.

This should fix #280

Hi @Nicolas-Gth , I gave it a try but sometimes the song text overlap with the commands and I keep getting binding loop errors.
I noticed that the ScrollingText component has become really hard to maintain and I was thinking to rewrite it completely.
I’ll try to tackle it next week.

That is strange. But I agree I see a lot of issues linked to it, so good luck!
