feat(aiturk): one-click sign-in for AITURK IDE (1.0.0-beta.14)

The onboarding and provider settings get a Sign in button: the IDE shows a
short code, opens the turkservis.online approval page, and after approval
saves the TurkServis provider itself and hands a separate member key to the
AITURK CLI over stdin (aiturk login --key-stdin --keep-other-account).
Keys never reach the renderer, logs, process arguments or URLs. Pasting an
API key remains as the fallback.
