### What Changes
- Fixed incorrect edgeless viewport display in peek view
- Moved page block viewport fit animation logic from `EdgelessRootBlockComponent` to note config extension
- Disabled page block viewport fit animation in peek view, using default `fitToScreen` instead
- @doodlewind Fixed viewport resizing issues by adding a immediate update mechanism to ensure proper rendering during peek view operations. The setViewportByBound is only called once during peek view initialization, so there are barely perf overhead.
- Updated related test cases
- Refactored peek view test cases to make them clearer and more reliable
- Added new test helper function `getViewportBound` for getting viewport boundary information
