Refactor modal components and enhance FormActionBar functionality

- Updated modal components to utilize a consistent overlay and panel structure, improving layout and responsiveness.
- Enhanced FormActionBar to support short labels for action buttons, improving usability in mobile views.
- Introduced new styling for action buttons and modal titles, ensuring better alignment and visual consistency across forms.
- Improved accessibility by adding aria-labels and titles to buttons for better screen reader support.
