test(e2e): switch organization-provided LLM profiles

[saurya]

Migration

Ports https://github.com/OpenHands/saas-deploy/pull/592 from OpenHands/saas-deploy so the test ships with the OpenHands-Cloud chart release it validates.

This pull request is based directly on main, which includes the foundational Playwright harness from OpenHands-Cloud #1048.

Original scenario contract

Scenario

Covers a member switching a live Canvas conversation between two LLM profiles supplied through the organization-scoped profile endpoint.

Environment contract

• BASE_URL: required non-production OHE deployment; production is rejected.
• e2e_tests/fixtures/auth.json: authenticated member storage state.
• TEST_ORG_LLM_PROFILE_ONE: first org-admin-configured profile visible to the member.
• TEST_ORG_LLM_PROFILE_TWO: second, different org-admin-configured profile.
• TEST_LLM_SWITCH_PROMPT: harmless conversation launch prompt.

The test proves both names came from /api/organizations/{org}/profiles and throws actionable errors rather than skipping.

Cleanup and isolation

• Switches the conversation to both configured profiles and verifies backend active_profile after each switch.
• Proves conversation switching did not change the member's global active profile.
• Deletes the created conversation in finally.
• Adds one spec with one test; shared harness files are unchanged.

Validation

• npm ci once: passed.
• npm run lint: blocked by 15 pre-existing errors in existing page objects and smoke.spec.ts; the new file is clean.
• Focused ESLint, Prettier, and tsc --noEmit: passed.
• Playwright --list: passed.
• Live execution unavailable locally because the auth fixture and configured organization profiles were absent.

Port validation

• Exactly one changed file: e2e_tests/tests/member-switch-org-llm-profiles.spec.ts.
• Exactly one Playwright test in the spec.
• Focused ESLint and Prettier checks passed.
• tsc --noEmit passed against the Cloud harness.
• Chromium Playwright --list discovery passed.
• Live execution still requires the explicit authentication and TEST_* contracts documented above.
