### Problem
●In edgeless mode, when starting to edit, `note-block` exhibits two
types of invalid caret behavior:
(1)**Title Region Misalignment**: Clicking on the title region
incorrectly generates the caret in the first line of the note content,
rather than in the title itself.
(2)**Vanishing Caret at Line End**: When clicking in the empty space
beyond the end of a text section, the caret appears momentarily at the
line's end but disappears immediately.
●The following video demonstrates these issues:
https://github.com/user-attachments/assets/db9c2c50-709f-4d32-912c-0f01841d2024
### Solution
●**Title Click Interception**: Added a check to determine if the click
coordinates fall in the title region. If so, the caret positioning is
now handled by a dedicated logic path. Otherwise, it falls back to the
existing note-content logic as before.
●**Range Normalization**: When the generated `range.startContainer` is
not a `TextNode`, try to find a most appropriate `TextNode` and update
the `range` accordingly.
### After
●The video below shows the behavior after this fix.

## Summary by CodeRabbit
* **Bug Fixes**
* Clicking a page block title no longer creates unwanted paragraphs and
reliably focuses the title.
* Paragraph creation now occurs only when needed and focus is applied
only after successful creation.
* Click coordinates are clamped to container bounds to prevent misplaced
cursors or focus.
* **Improvements**
* Caret normalization: clicks place the caret at the last meaningful
text position for consistent single-cursor behavior.
* **Tests**
* Added end-to-end coverage for caret placement and focus transitions.
* New ratio-based click/double-click test utilities and a helper for
double-clicking note bodies.

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.

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.

## Fix Shape Tool Issues
This PR addresses several issues with the shape and mindmap tools functionality in the editor:
1. **Fix text editing after mode switching**: Resolves an issue where users couldn't edit text in shapes after switching editor modes. The fix ensures the edgeless block is properly retrieved when double-clicking on a shape.
2. **Improve tool switching behavior**: Fixes issues with tool overlays not showing or being repeated when switching between tools. This includes:
- Properly handling tool overlay visibility
- Ensuring only one tool is active at a time when using keyboard shortcuts
- Adding proper cleanup when switching tools
3. **Add comprehensive tests**: Adds new test cases to verify:
- Shape creation with keyboard shortcuts
- Shape text editing after mode switching
- Tool switching behavior with keyboard shortcuts
