- Escape HTML in _render_error to prevent XSS from exception messages
- Replace asyncio.create_task/sleep with anyio task group and sleep,
tying poll task lifetime to the app lifespan for proper cleanup
- Extract rewrite_url_origin() utility to fix duplicated URL rewriting
logic and replace urlparse._replace with stable urlunparse API
- Add warning log for insecure HTTP redirect URIs
- Add unit tests for validation, XSS escaping, route handlers, and
URL rewriting (16 new tests in test_provision_routes.py)

Nextcloud may omit default ports in the login_url (e.g. http://app
instead of http://app:80). Extract just scheme+hostname from
NEXTCLOUD_HOST for the URL replacement check.

Replace the popup-based approach with a direct redirect to Nextcloud's
login page. This is more compatible with Playwright E2E tests and
simpler for users. The background polling task still runs server-side
to store the app password when the user grants access.

Add /app/provision and /app/provision/status endpoints for browser-based
Login Flow v2 app password provisioning. Used by Astrolabe's "Enable
Semantic Search" to chain OAuth (bearer token) + Login Flow v2 (app
password) in a single user interaction.
The provision page initiates Login Flow v2, opens Nextcloud's login URL
in a popup, polls for completion via background task, and redirects back
to the caller's redirect_uri on success.
