A frozen mirror's notice and reconnect form draw §5's card, row and btn, and .frozen, .frozen-form, .frozen-sentence leave the markup #4187

A frozen mirror's notice and reconnect form are now drawn with §5's card, row and field-row. None of .frozen, .frozen-form or .frozen-sentence appears in the page's HTML any more. bun test test/origins-reconnect.test.ts test/design-lint.test.ts passes (22 tests). bun x tsc --noEmit could not run: it fails here with Cannot find type definition file for 'bun', even after bun install.

What changed (src/web/pages/frozen.ts, test/origins-reconnect.test.ts)

• frozenBlock returns a card with pad: false holding a ul.list of li.row rows. The first row is the sentence. The second is whichever of three actions applies: the Reconnect form for an admin with a matching origin, the "Connect an account under Settings → Origins" link for an admin without one, or "An admin of this repository can reconnect it." for a non-admin.
• The id="frozen" anchor stays, because the fork page links to #frozen.
• The form still posts origin to …/settings/origin/reconnect, with the same select, label and "Reconnect" button. Its class is now field-row.
• The tests assert the old class names are absent from the page. They also assert the sentence, the form action, name="origin", the origin option, "Reconnect through" and the "Reconnect" button are present. The other two actions' wording was already asserted and still passes.

What I left alone

• The .frozen* rules in src/web/style/content.ts and docs/DESIGN.md, as the issue says; that is part two.
• The old margin-top: 12px on the block and the select's flex sizing went with those rules. Spacing may differ slightly until part two, and I had no browser here to check it.

To try it

• Open a frozen mirror's home or branches page as its admin.
• Or run bun test test/origins-reconnect.test.ts.
