fix(e2e): add paginated mock for /api/invoices and remove fragile networkidle wait

- Return { data: [], total: 0 } for /api/invoices instead of falling through to generic []
- Removes waitForLoadState('networkidle') from admin invoices test (fragile in CI)
- Fixes GRO-558

-## Development
-
-- Package manager: `pnpm` (workspace monorepo)
-- Run E2E tests: `pnpm --filter @groombook/e2e test`
-- Run API: `pnpm --filter @groombook/api dev`
-- Run web: `pnpm --filter @groombook/web dev`
-
-## Git Workflow
-
-- Branch from `main` using the pattern `fix/<issue-id>-<short-desc>` or `feat/<issue-id>-<short-desc>`
-- Push to origin and open a PR against `main`
-- If the issue specifies an existing PR/branch, push to that branch instead of creating a new one
-- Commit messages: short imperative summary, reference the issue ID

-## Task Handoff (Paperclip)
-
-When you receive an assigned task from Paperclip:
-
-1. **Checkout the task** immediately using `POST /api/issues/{issueId}/checkout`
-2. **Read the full issue description** and any comments for context
-3. **Do the work** — implement the fix/feature as described
-4. **Test your changes** — run relevant tests, lint, type-check
-5. **Commit and push** your changes to the appropriate branch
-6. **Update the task** with status `in_review` and a comment summarizing what you did, including the commit SHA and PR link
-7. **Never leave a task in `in_progress` without posting a comment** explaining current state before exiting your heartbeat
-
-If you cannot complete the work (missing info, blocked by another task, environment issue):
-- Set the task to `blocked` with a comment explaining what's blocking you
-- Tag your manager in the comment if escalation is needed
-
-Do NOT silently drop tasks. Every assigned task must get a status update and comment before your heartbeat ends.
