Update login page theme to match makima.jp visual design

Replace generic zinc Tailwind colors with the blue-themed colors used
throughout makima.jp:
- Form container now uses panel class with blue borders
- Input fields use bg-[#0f1c2f] and border-[#2f476d] colors
- Labels updated to text-[#9bc3ff] (text-secondary)
- Mode switcher tabs use blue accents instead of white
- Submit button styled with blue primary (#0f3c78) background
- Headings use text-[#f0f5ff] for consistency
- Auth not configured message also themed
