Canvas bugfixes and UX improvements

What's Changed

This release addresses several bugs and introduces user experience improvements related to the canvas, file handling, and the onboarding tour.

• Improved File Attachment: The file attachment process in both the main chat input and the inline editor has been refactored to use a native file open dialog. This provides a more reliable and standard user experience compared to the previous hidden file input method.
• Enhanced Image Insertion: The "Insert Image" functionality in the WYSIWYG editor has been updated to work with local file paths instead of URLs, making it easier to embed local images into documents. The editor now also correctly preserves the user's cursor position after an image is inserted.
• Canvas Visibility Shortcut: A new keyboard shortcut (Cmd/Ctrl+Shift+C) has been added to quickly toggle the visibility of the canvas, improving workflow efficiency.
• UI Refinements:
  • The WYSIWYG editor container now has a cleaner, borderless design to better integrate with the UI.
  • The tooltip for the "Open Canvas" button now displays the new keyboard shortcut.
• Onboarding Tour Updates: The onboarding tour has been updated with a new image and more descriptive text to provide a better introduction for new users.

Impact

• No Breaking Changes: These changes are non-breaking and focus on improving existing functionality.
• Improved User Experience: The new file dialog and keyboard shortcut make common actions more intuitive and faster.
