feat(web): show the pairing code before the sign-in link

[defangdevs]

Motivation

In the Connections cards, the sign-in wizard listed the link first and the pairing code second:

1. [Open the sign-in page] and approve the request.
2. Enter this code on that page: 56D0-6G7MP [copy]

So the user opened the sign-in page, found it wanted a code, and had to come back to the settings page to press the copy button - a tab switch in each direction, on the surface most likely to be read from a phone. The copy widget was there; it was just on the wrong side of the link.

Change

Steps now run in the order the hands move:

1. Copy this code: 56D0-6G7MP  [copy]
2. Open the sign-in page and paste the code.
3. Paste the code the page gives you back      (only for flows that ask for one)

The link's trailing prose follows the code: "and paste the code" when there is one, "and approve the request" when there is not. A flow with no code of its own (claude) is unchanged - the link is step 1 and the numbering leaves no gap, so needs_code still lands on 2 there and on 3 for codex/gh.

render_connect_step() numbers the steps from a counter instead of hard-coded literals, which is what removes the old "3" if state["code"] else "2".

User-visible and security effects

Copy change and step order only. No flow, no route, no credential path is touched: the pane is still the state, the code still comes from CONNECT_CODE_RE over the pane, and the copy button is the same copy_button() helper used elsewhere on the page.

Checks run

All 30 aarch64-linux flake checks, in one nix build --keep-going, exit status captured without a pipe: status=0. Includes golden-snapshot, module-generated-up-to-date, connect-card, backend-parity and one-spec-both-backends.

Regenerated and committed alongside: nix run .#assemble (the module) and nix run .#update-golden (the settings payload). settings-daemon.py is a web-only payload, so tests/native/expected/ does not move - confirmed by python3 tests/test_agentbox.py (exit 0).

Also rendered render_connect_step() directly against the golden payload for the three shapes (code + needs_code, code only, no code) and read the markup, per the repo's "render the function directly" rule. No test asserts this copy, so nothing needed loosening.

No screenshot

This box's chromium aborts (SIGABRT) inside Page.captureScreenshot and in one-shot --screenshot mode alike - four flag combinations, including --disable-gpu, --in-process-gpu --use-angle=swiftshader and CDP over a long-lived browser. Unrelated to this change; the rendered markup above is what the three shapes produce.

📝 Walkthrough

Walkthrough

The pairing wizard now places code copying before sign-in, uses dynamic step numbering, and changes the sign-in text based on whether a pairing code exists. The Nix module, daemon implementation, and golden payload reflect the same flow.

Changes

Pairing wizard flow

Layer / File(s)	Summary
Dynamic pairing steps modules/src/settings-daemon.py, modules/agent-box.nix, tests/golden/web/payloads/agent-box-settings/bin/agent-box-settings	The wizard renders the copy-code step before the sign-in link when a code exists. The link says “and paste the code” or “and approve the request”. A counter supplies the current and later step numbers across the implementation and golden payload.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 66f00

Claude connection users may be told to approve the request even though completing the flow requires copying a returned code and submitting it. This contradictory guidance can prevent successful sign-in and should be corrected before merge.
