fix: 🎨 Improve readability of long error messages in ErrorBoundary dialog

[wapec]

• white-space: pre-wrap for stack-trace newlines and indentation
• -webkit-line-clamp increase from 7 to 12 for more context per dialog
• drop redundant max-height

How to trigger the dialog

Open any mobile editor, then in the editor iframe's DevTools console:

(() => {
    const app = document.getElementById('app');
    const reactKey = Object.keys(app).find(k => k.startsWith('__reactContainer'));
    const find = f => {
        if (!f) return null;
        const n = f.stateNode, t = f.type;
        if (n && typeof n.componentDidCatch === 'function' && typeof t?.getDerivedStateFromError === 'function') return n;
        return find(f.child) || find(f.sibling);
    };
    const eb = find(app[reactKey].stateNode.current);
    eb.componentDidCatch(new Error(
        "ReferenceError: someVariable is not defined\n" +
        "    at Object.handleClick (app.js:12345:67)\n" +
        "    at HTMLButtonElement.onClick (Component.jsx:42:18)\n" +
        "    at executeDispatch (react-dom.production.min.js:5481:9)\n" +
        "    at processDispatchQueue (react-dom.production.min.js:5512:9)"
    ));
})();

Before / after — last line clipping

Before (max-height: 120px, clamp 7)	After (no max-height, clamp 12, pre-wrap)

Test checklist

• Stack-trace lines render on separate rows with indentation
• Last visible line is fully shown or replaced by …, not half-clipped
• Short texts are shown in the same way as before

Two small follow-up items from the review:

A very long unbroken token (e.g. a minified URL in a stack frame) won't wrap at a word boundary with overflow-wrap: break-word alone — it only breaks at word boundaries. Adding word-break: break-all ensures any run of non-space characters is also wrapped.

Suggested change

	white-space: pre-wrap;
	overflow-wrap: break-word;
	word-break: break-all;

This rule is shared by all four mobile editors (documenteditor, spreadsheeteditor, presentationeditor, visioeditor). Worth ticking the checklist against each one before merging, not just the one used for the test script above.
