ci(e2e): include debug screenshots in maestro artifacts upload

The takeScreenshot commands in common/sign-in-email-password.yaml DID
execute (Maestro log confirms COMPLETED on each), but Maestro saves them
relative to its cwd (integration-mobile/) rather than ~/.maestro/tests.
The upload-artifact step only grabbed the latter, so the debug-01-welcome,
debug-02-email-typed, and debug-03-after-continue captures were stranded
on the runner.

Add integration-mobile/*.png to both platforms' artifact upload paths.
