xli-oai 8d5da3ffe5 Fallback login callback port when default is busy (#19334) ...

## Summary
- Keep the preferred ChatGPT login callback port `1455` first.
- Preserve the existing `/cancel` recovery for stale Codex login
servers.
- Fall back to the registered localhost callback port `1457` when `1455`
remains unavailable.

## Why
Cursor and Codex Desktop both use the ChatGPT account login callback
server. On Windows, Cursor can already be listening on `127.0.0.1:1455`
/ `[::1]:1455`, causing Codex Desktop sign-in to fail with:

`Local callback port 1455 is already in use on this machine.`

Codex already attempted to cancel a stale Codex login server on that
port, but if the listener does not release the port, the old behavior
was to fail. The new behavior falls back to `1457`, which matches the
fixed redirect URI being registered server-side in
`openai/openai#863817`. This keeps the OAuth `redirect_uri` inside
Hydra's exact allow-list instead of choosing an arbitrary ephemeral
port.

## Validation
- `just fmt`
- `cargo test -p codex-login`
- `git diff --check HEAD~1..HEAD`
