Close [BS-3426](https://linear.app/affine-design/issue/BS-3426/frame-修改背景色后不能撤销)
This PR fixes the issue where the color change of edgeless blocks could not be undone/redone, including notes, edgeless-text, and frames. It also addresses the problem of a tiny shape being unexpectedly retained on the canvas. The key changes are:
- Removal of `transact` from the `pop` method of edgeless elements.
- Refactoring of `onPickColor` for all edgeless elements and blocks to better control the lifecycle of custom color property changes.
- Addition of the missing custom background color feature for notes.
- Addition of undo/redo color tests for notes, frames, and edgeless-text.
