A warmer, friendlier admin: first pass

- The INBUXA palette on warm surfaces, softer cards, buttons and inputs, and
  self-hosted Inter and Space Grotesk.
- Each section's icon sits on a colored tile, colored by what the section is
  about.
- The sidebar gets a guide line for sub-pages and a labeled Management /
  Settings / Account switch, and folds to a rail of tiles (remembered).
- Every page has a header with its section's tile.
- Fields and pages with no label of their own are spelled out in words
  (defaultCertificateId becomes Default certificate ID).
- The dashboard greets you, and its stat cards wear colored tiles.
- Unavailable live numbers are a calm note, not an error.
- The cat appears in empty lists and while loading.
- Chart colors work again: they were hex values wrapped in hsl().
