Dark Mode for the Ipregistry Dashboard

We’ve introduced a new dark theme across the Ipregistry dashboard to improve comfort and provide a more modern, focused interface:

Full dark UI across navigation, charts, and billing views

Improved contrast for API usage graphs and key metrics

Automatic preference detection based on your system theme

Manual toggle available from the top-right theme switcher

Dark mode reduces eye strain during extended monitoring and better fits low-light environments while keeping all analytics and usage insights clearly readable.

No functional changes, only visual enhancements.
