feat(kilo-console): align fonts with Kilo Cloud

Kilo Console was rendering the OS sans/mono fallback stack instead of
Inter / Roboto Mono / JetBrains Mono like Kilo Cloud. Kilo Cloud's web
app (apps/web/src/app/layout.tsx) loads these via `next/font/google`,
but Kilo Console is a Vite-built SolidJS SPA that can't fetch Google
Fonts at build time the same way.

Changes:

- Self-host Inter Variable, Roboto Mono Variable, and JetBrains Mono
  Variable as woff2 under packages/kilo-web-ui/src/assets/fonts/.
  All three are OFL-1.1; attribution added next to the files.

- Add @font-face blocks at the top of
  packages/kilo-web-ui/src/styles/theme.css for the three variable
  fonts. The blocks live outside the scoped [data-theme="kilo"]
  selector so they're available everywhere Kilo Web UI styles load.

- Declare the three Cloud-mirror tokens in the same scoped block where
  --font-family-sans/-mono are already overridden:
    --font-sans-loaded  -> "Inter Variable"
    --font-mono-loaded  -> "Roboto Mono Variable"
    --font-jetbrains    -> "JetBrains Mono Variable"
  Re-alias --font-family-sans/-font-family-mono to point at the new
  tokens, so all existing var(--font-family-*) consumers across the
  200+ call sites in kilo-ui, kilo-web-ui, and kilo-console pick up the
  new fonts with no per-site change.

- Drop three hard-coded inline fallbacks in kilo-console styles
  (base.css, profile.css, resolved.css) that named "Inter" directly,
  so the value flows through the cascade instead of short-circuiting it.

- No upstream changes: packages/ui/* (the @opencode-ai/ui fork) is
  untouched, avoiding kilocode_change markers in shared files.

Verified with `bun run build` in packages/kilo-console (all four
@font-face blocks emitted to the bundled CSS with hashed woff2 URLs)
and `bun run typecheck` in both kilo-console and kilo-web-ui.

+Use the same font stack as Kilo Cloud (Inter variable for sans, Roboto Mono variable for mono, JetBrains Mono variable as the alt-mono token) in Kilo Console. Fonts are now self-hosted as woff2 in `@kilocode/kilo-web-ui`, so Inter no longer relies on the OS having it installed.
