Incorrect Resize Behavior for Pasted Chips

What are you trying to accomplish?

Fix incorrect resize behavior for pasted inline work package chips.When a chip was copied and pasted,

BlockNote duplicated all props verbatim - including instanceId. Since wpBridge routes resize/delete actions by instanceId, two chips with the same ID caused every action to always affect the first chip in the document, not the intended one.

What approach did you choose and why?

Registered a ProseMirror transformPasted plugin (pasteDeduplicatePlugin) that intercepts pasted content before it enters the document and regenerates instanceId for every inline WP chip found in the slice.

Also updated the host application (OpBlockNoteEditor) to call useDeduplicateInstanceIds: opf/openproject#22969

This is the correct hook for this problem - it prevents the duplicate from ever existing rather than cleaning it up after the fact. The plugin is registered via _tiptapEditor.registerPlugin(), following the same pattern already established in BlockWorkPackageComponent for selectionUpdate.

Alternative considered: an onChange listener that scans for duplicate instanceId values and patches them post-insert. Discarded because it runs on every editor change, has a window where the document is in an inconsistent state, and requires a guard to prevent infinite loops from its own updateBlock calls.

Merge checklist

• Added/updated tests
• Added/updated documentation in Lookbook (patterns, previews, etc)
• Tested major browsers (Chrome, Firefox, Edge, ...)
