kolaente 649043aceb test: add tests for OAuth 2.0 authorization flow
Add web tests covering the authorize endpoint, token exchange, PKCE
verification, single-use codes, and refresh token rotation. Add unit
tests for redirect URI validation and PKCE. Add E2E test for the full
browser-based authorization code flow with login redirect.

Extract setupApiUrl helper for E2E tests to avoid duplication.
