bug: E2E regression after PR #240 — members invite test expects removed "Invite sent." text

[zacharias-ona]

Description

PR #240 ("feat: show copyable invite link in pending invites list (#239)") replaced the "Invite sent." success message in the invite form with an inline invite link display. The E2E test members.spec.ts > owner can invite a user by email expects text=Invite sent. to be visible after submitting an invite, but that text no longer exists in the component.

This causes the members test to fail, which also blocks 6 dependent serial tests in the same describe block.

Two other E2E failures were observed but are not related to this PR:

• search.spec.ts > search with no matches shows empty state — pre-existing empty state text mismatch
• workspace-settings.spec.ts > personal workspace shows 'cannot be deleted' message — test environment issue (resolveTestUserId fails because Supabase admin listUsers doesn't find the test user)

Acceptance Criteria

• Update e2e/members.spec.ts to match the new invite form behavior (invite link shown instead of "Invite sent." text)
• All 7 serial members tests pass against production
• pnpm lint && pnpm typecheck && pnpm test pass

Technical Notes

• PR that introduced the regression: feat: show copyable invite link in pending invites list (#239) #240
• Affected file: e2e/members.spec.ts lines 110 and 159
• The invite form (src/components/members/invite-form.tsx) now shows a copyable invite URL after successful submission instead of the "Invite sent." toast/text
• The test should assert on the new invite link element or updated success indicator
• The "Invite sent." text also appears in the re-invite test at line 159 — both assertions need updating
