New look: one design system on every screen

What changed

• Main action buttons use the brand blue; the side menu, the sign-in panel and the portal header are deep navy.
• Headings and key figures use a more readable typeface; body text in the workspace is slightly larger.
• The choice controls on the calendar, case, quote, payment and settings screens now share one component, and toolbars no longer overflow on a phone.
• The product screenshots on the website were retaken in the new design in Turkish and English; the portal's form, payment plan and trip screens were added.
