On mobile, pasting a full pairing link such as http://100.82.53.91:3773/pair#token=… into Add environment → Address keeps the whole link in Address and leaves Code empty. Desktop's Add environment dialog splits the same paste into the server address and the pairing code. If Code already holds an older code, mobile submits that stale code instead of the link's token.
Repro: on a remote machine, create a pairing link. On mobile, open Settings → Environments → Add environment and paste the link into Address.
handleHostChange in ConnectionsNewRouteScreen.tsx runs the existing parsePairingUrl on each Address change. When the value contains a token, both fields are set from the parsed host and code. Otherwise the raw edit is kept and Code is left alone, so typing, editing, or clearing an address never touches a manually entered code. This matches desktop's handleSavedBackendHostChange.
No parser, contract, server, or web changes. Both mobile entry points (ConnectionsNew and SettingsEnvironmentNew) render this form. QR scanning keeps its own path.
A small fix for an obvious bug: mobile's Add environment form doesn't handle the pasted pairing link the way desktop does.

Macroscope's review found this PR approvable — Pasting a pairing link into Address now fills both Address and Code using the existing parser. Connection still requires explicit submission, keeping the change limited to form entry.

The connection form now parses pairing URLs entered in the Address field. When parsing finds a code, the form updates both the host and code. Tests cover pasted URLs and verify that later Address edits preserve a manually entered code.

Keep partially typed pairing links in the Address field.
When a user types a pairing URL, the first token character makes pairing.code nonempty. The handler then replaces the Address with the host, so later characters no longer extend the token. The previous handler allowed the complete URL to be submitted when Code was empty. (raw.githubusercontent.com)
Distinguish a paste from incremental typing, or defer extraction for incremental edits.

Desktop's Add environment dialog (handleSavedBackendHostChange) splits on every change in the same way. This PR brings mobile in line with that. Typing a full pairing link by hand on a phone isn't a realistic path, since the link is pasted or scanned and a hand-typed code goes in the Code field. The split is also visible before submit, so it can't silently connect with a truncated code. Leaving this as is to keep the two clients consistent.
@Padi142 Understood. Pairing links are intended to be pasted or scanned, while manually entered codes use the Code field. The split is visible before submission. I withdraw the request to distinguish pasting from incremental typing.
