fix(auth): make the sign-in screen readable, and draw it in the product's design language (#338)

## Why

Two separate faults on the same screen, found while trying to sign in
for the first time.

**The email field was unreadable.** `[data-component='input']` computed
its own background one step lighter than the page and never set `color`.
Form controls do not inherit it, so the text someone typed was the UA
default — black glyphs over a near-black field. There was no
`color-scheme` either, so the browser rendered the control in light
appearance to begin with. That rule was the only `input` selector in the
stylesheet.

**The screen was still the upstream template's** — its font, its accent,
its logo. `issuer()` takes a `theme` and calls `setTheme`, but nothing
had passed one since `packages/auth` became a vendored fork.

## What changed

The theme is restored and the page is redrawn in the design language the
rest of the product uses: black, a neutral grey ramp, one brand accent,
Mona Sans for the display line and Geist for anything read or typed, two
dashed bands closing into a box on a wide screen, a dashed vertical
either side of the column, the wordmark, and the line of copy the
product opens with.

**Dark only.** The scheme that let one theme serve both light and dark
derived every colour from the background's lightness through `oklch(from
...)`, and that derivation is exactly what left the field's text the
colour of its own background. Values are now stated, not computed.

The brand colour appears in two places: the wordmark, and the field's
border on focus.

## Evidence

Measured against a render of the same design built from its own source,
at 1280×900:

| | reference | this |
|---|---|---|
| band rules | y `79`, `820` | y `79`, `820` |
| column rules | x `106`, `1172` | x `106`, `1172` |
| wordmark box | x `505–774`, h `45` | x `505–774`, h `45` |
| heading span | `66px` | `66px` |
| button height | `60px` | `60px` |

Both screens (email and code) and a 390px viewport were rendered and
looked at, not just diffed.

`bun test packages/auth` → 66 pass, 0 fail. Typecheck, `oxfmt` and
`oxlint` clean.

## What this does not verify

- **Nothing has been signed in with.** The screens were rendered
directly from `CodeUI`; no code has been minted, mailed or redeemed
through this page. That is the next thing, and it happens on
`auth.nestri.io` after this merges.
- **Fonts are a new third-party runtime dependency on the sign-in
path.** Mona Sans and Geist come from the jsdelivr Fontsource CDN,
because self-hosted font packages need a bundler and nothing
preprocesses this page. If jsdelivr is unreachable the page falls back
to `system-ui` and stays usable, but serving them from our own origin is
probably the right end state.
- **Only Chromium was used.** The autofill rules are `-webkit-` prefixed
and were reasoned about, not observed; no Firefox or Safari render was
taken.
- **`docs/deploy.md` is stale** and not touched here. It still says
Cloudflare Workers is "what production and sandbox are today";
production is long-lived processes on a VM behind a tunnel. Worth a
separate change.
