This PR addresses issue Fixes: #13805 (cross-document copy/paste not
working).
Locally verified that:
- Copy → paste between two documents now works consistently.
- Clipboard snapshot payload remains intact when encoded/decoded.
- External paste (e.g., to Notepad or browser text field) functions
correctly.
E2E tests for clipboard behavior were added, but Playwright browsers
could not be installed in the container (`HTTP 403` from CDN).
Manual verification confirms the fix works as intended.

## Summary by CodeRabbit
* **Tests**
* Added cross-document clipboard regression tests for copy/paste between
documents, external clipboard validation, and multi-block copy;
duplicate test entries noted.
* **Chores**
* Minor formatting and whitespace cleanup around clipboard handling.
* Improved error handling in paste flows.
* Standardized HTML formatting for clipboard payload attributes.

## Summary by CodeRabbit
- **New Features**
- When converting a note block to a linked document, the initial document title now uses the first paragraph in the note (if available) as a placeholder.
- **Tests**
- Updated tests to verify that the linked document creation modal pre-fills the title with the note's first paragraph and checks for correct paragraph order.

Sometimes, missing `await` in the test code can cause timing issues, leading to test failures. This PR enables the `no-floating-promises` rule for the test code to ensure that such errors do not occur.
### What Changes
- Refactors the `notify` function call with undo button. It is called `notifyWithUndo`, which can associate the visibility of the `NotificationCard` with the top undo item in history stack, such as undo by shortcut `Cmd+Z`.
- change icon of the "Insert into page" button. Close [BS-3267](https://linear.app/affine-design/issue/BS-3267/frame和group的insert-into-page图标也更换一下)
### TL;DR
Prevent pasting content when a document is in readonly mode.
### What changed?
Added a check in the `PageClipboard` class to prevent pasting operations when the document is in readonly mode. The function now returns early if `this.std.store.readonly` is true, preventing any clipboard operations from being executed.
### How to test?
1. Open a document and add some content
2. Set the document to readonly mode: `document.querySelector('affine-page-root')!.doc.readonly = true`
3. Try to paste content into the document using:
- Regular paste operation
- Keyboard shortcut (Ctrl+V/Cmd+V)
4. Verify that no content is pasted and the document remains unchanged
5. Set the document back to editable mode and confirm pasting works again
### Why make this change?
This change ensures that documents in readonly mode maintain their integrity by preventing unintended modifications through clipboard operations. This is consistent with the expected behavior of readonly documents, where users should not be able to modify content through any means.
