The terminal line on the account and site pages draws §5's code and row, and .terminal-line leaves the markup #4249

The terminal line on the account keys page and the site Terminal card no longer carries .terminal-line in its HTML. It's now drawn with §5's .stack.stack-tight, a <code class="mono break"> for the command, and .muted.small.break for the host key. The tests I ran pass: test/ssh-site.test.ts, test/design-lint.test.ts, test/apps.test.ts and test/studio. I couldn't run the type check: bun x tsc --noEmit stops on "Cannot find type definition file for 'bun'" in this sandbox, and I saw no other type errors.

• Shared helper: terminalLine() in src/web/ui.ts is also used by the app page, the previews page and the studio home, so those lose .terminal-line too. It now builds on a new terminalCommand(command, fingerprint?, extra?).
• Account keys page: src/web/pages/account.ts wraps terminalCommand in <div class="mb" id="terminal">. The "terminal is off" paragraph is unchanged.
• Site Terminal card: src/web/pages/site.ts passes the "SSH keys" link in as extra, so it now sits below the command instead of beside it.
• Same words and links: The command is still printed verbatim from FORGE_APP_SSH inside the email_off markers.
• No new rules: I added no CSS and no width rule, and I left style/content.ts and docs/DESIGN.md alone for part two. Inputs are untouched.
• Not a §5 row: I did not use row(), because .row-title is single-line with an ellipsis and would truncate the command people copy.
• Tests:

- test/ssh-site.test.ts previously asserted that the landing page contains terminal-line; it now asserts the opposite. - The keys-page test asserts terminal-line is absent and id="terminal", the host key and <code class="mono break"> are present. - A new test checks the dashboard card for the "SSH keys" link and the host key. - test/apps.test.ts:914 expected <code class="mono">; I updated it to mono break, since the markup is meant to change.
