Apply technical-light design system to the gateway dashboard

Restyles the Blazor dashboard onto a portable token-based theme so it reads like an instrument panel: warm-paper background, hairline-ruled panels, IBM Plex type, monospace tabular numerics, and status carried by colour chips. Vendors theme.css + IBM Plex fonts, rewrites dashboard.css as a thin token-driven view layer, and swaps the Bootstrap navbar and status badges for the design-system app bar and chips. Also includes pending API-key management, Galaxy hierarchy projection, and constraint-enforcement work with their tests. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
