Closes #271.

Adds frontend/app/(workspace)/settings/integrations-api.test.ts, covering every exported function in integrations-api.ts. It stubs fetch and window the same way lib/create-run.test.ts does, so backendFetch takes its browser path.

• fetchIntegrations: reads /api/integrations with cache: "no-store" and decodes the list; throws on a non-OK response
• startIntegrationConnect: GitHub and Slack use the /org path while other apps don't; the provider is URL-encoded; posts the returnTo body; returns expiresAt: null when the backend omits it; throws on a non-OK response; throws when redirectUrl or state is missing or blank
• completeIntegrationConnect: posts the state and callback, and leaves callback out when there is none; returns null on 400 and 409; throws on other errors; throws when the answer has no usable connection
• disconnectIntegration: DELETE on the /org path for GitHub and Slack and the user path otherwise, with the connection id encoded; throws on a non-OK response

No source changes.

Checks

$ cd frontend && bun test "app/(workspace)/settings/integrations-api.test.ts"
 15 pass
 0 fail
 29 expect() calls

To check the tests catch real regressions, I temporarily changed the source so Slack skipped the /org path and 409 stopped counting as pending: 3 tests failed (the org-path connect, pending callback and org-path disconnect tests), then passed again once restored.

bun run lint and bun run typecheck in frontend pass.
