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
