fix(security): parse and compare hostname instead of substring match in Adobe Firefly login

Replace request.url.includes(FIREFLY_3P_HOST_SUFFIX) with parsed-hostname
comparison (anchored endsWith), closing CodeQL alert #778.

The old substring check could be bypassed by an attacker-controlled page
visited during the browser login window — a URL like
'https://evil.com/firefly-3p.ff.adobe.io' would pass the gate and its
Bearer token would be captured as the Adobe credential.

Practical severity is low (only during operator-initiated, time-boxed
login on a temp-profile browser), but the fix is one line and matches
the dot-anchored idiom used in docker/devin-bridge/network-guard/.

Closes code-scanning #778.
