2920 - Add drag and drop support for data pills into property inputs

[petrapaz]

fixes: #2920

• Enable dragging data pills from the Data Pill Panel and dropping them into PropertyMentionsInput editors to insert mention nodes at the drop position. Extract shared validation logic into canInsertMentionForProperty utility to eliminate duplication between click and drop insertion paths.

• Add visual drop-target feedback (green highlight) on property inputs during drag using isDraggingDataPill state in Zustand store

• Extract shared validation logic (canInsertMentionForProperty) into encodingUtils.ts to eliminate duplication between click-to-insert and drop-to-insert code paths

• dynamic value has to be enabled for drag & drop to work

Evo jedan relativno bitan komentar od mog Claude-a (koji ja ne bi uvatija)

1. resolvePath can throw on invalid paths (Medium)

canInsertMentionForProperty calls resolvePath(parameters, resolvedPath), which throws on invalid paths (the object-resolve-path library throws on invalid paths). In the old code this would also bubble up unhandled, but in the new handleDrop code path this could silently break drop behavior. Consider wrapping in a try/catch:

export const canInsertMentionForProperty = (
    propertyType: string,
    parameters: Record<string, unknown>,
    path: string
): boolean => {
    if (propertyType === 'STRING') {
        return true;
    }

    try {
        const resolvedPath = transformPathForObjectAccess(encodePath(path));
        const existingValue = resolvePath(parameters, resolvedPath);

        return !existingValue || String(existingValue).startsWith('=');
    } catch {
        return true;
    }
};

Zanima me, zašto nam triba ovaj clone? Je li možda draggable dovoljan? Prvi put vidin, i čini se okej ali bi volija da i ja i ti znamo zašto nam je cloneNode potreban
