### Changed
- Better snapping when resize elements
<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit
- **New Features**
- Improved resizing behavior with enhanced alignment and snapping during element resizing, supporting rotation and multiple element selection.
- Alignment lines now display more accurately when resizing elements.
- **Refactor**
- Resizing logic updated to use scale factors instead of position deltas, enabling smoother and more precise resize operations.
- Resize event data now includes richer details about handle positions, scaling, and original bounds.
- Coordinate transformations and scaling now account for rotation and aspect ratio locking more robustly.
- Cursor updates are disabled during active resize or rotate interactions for a smoother user experience.
- **Tests**
- Updated resizing tests to use square shapes, ensuring consistent verification of aspect ratio maintenance.

### TL;DR
Fix presentation mode space-drag interaction by disabling black background during panning and properly restoring presentation state.
### What changed?
- Modified how the presentation tool handles state restoration after panning
- Disabled black background during space-drag and middle-mouse panning in presentation mode
- Fixed tool state management to properly restore presentation mode after space panning
- Added direct modification of the current tool's activated options instead of triggering a full tool change
### How to test?
1. Create a frame in edgeless mode
2. Enter presentation mode
3. Press space and drag to pan around
4. Verify the black background disappears during panning
5. Verify presentation mode is properly restored after releasing space
6. Try the same with middle-mouse button dragging
### Why make this change?
The black background in presentation mode was causing visibility issues during panning operations. Additionally, the presentation state wasn't being properly restored after space-drag panning. These changes improve the user experience by making content visible during navigation while maintaining the presentation mode state.

## Summary by CodeRabbit
- **New Features**
- Presentation mode now automatically hides the black background overlay when dragging with the space key or middle mouse button, improving visibility during navigation.
- **Bug Fixes**
- Improved handling of tool switching after panning in presentation mode, ensuring smoother transitions and state restoration.
- **Tests**
- Added an end-to-end test to verify that the black background is hidden during space-drag actions in presentation mode.

Before this PR, presentation mode would force quit if user either:
1. Press space
2. Drag with mouse middle button

## Summary by CodeRabbit
- **Bug Fixes**
- Improved presentation mode to preserve your current panned view when exiting pan mode or toggling fullscreen, preventing unwanted viewport resets.
- Spacebar actions are now correctly disabled when using the frame navigator tool, avoiding accidental tool switches.
- **New Features**
- Enhanced presentation controls for smoother transitions and better handling of user navigation states.
- Added a one-time toast notification for presentations without frames, shown only once per session for better user guidance.
