Subject: [PATCH 3/3] feat: Add theme system, beautify forms, fix bugs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Created global theme system with light/dark mode support
- Added CSS variables for colors, spacing, and typography
- Beautified form styles with improved spacing and borders
- Added theme toggle button to UI
- Fixed bug in docInfo: delete data.license instead of data.contact
- Improved variable naming: getData → getFormData, saveData → saveFormData
- Removed debug console.log statements from siderMenu
- Enhanced visual hierarchy and component styling
