test(e2e): use stable cron test ids

## Summary

- Adds shared `waitForTestId` and `clickTestId` E2E helpers for stable DOM hooks.
- Adds missing `cron-jobs-panel` and `cron-refresh` hooks to the Cron Jobs settings panel.
- Migrates the reference cron E2E flow away from Tailwind class/DOM walking to cron row/action test IDs.
- Documents the E2E `data-testid` naming taxonomy in the E2E guide.

## Problem

- #1861 calls out `cron-jobs-flow.spec.ts` as the concrete example of brittle selectors: it found `morning_briefing` via Tailwind class strings and `closest('div.p-4')`.
- That breaks on harmless class/layout refactors and makes the reference spec a weak template for future E2E work.

## Solution

- Use existing `CoreJobList` cron row/action hooks directly from the spec.
- Add the missing panel/refresh hooks so the whole cron flow can avoid text/button discovery for row actions.
- Centralize test ID waiting/clicking in `element-helpers.ts` instead of keeping local DOM snippets in specs.

## Submission Checklist

- [x] Tests added or updated (happy path + at least one failure / edge case) per [Testing Strategy](../gitbooks/developing/testing-strategy.md#failure-path-requirement) - updated the reference cron E2E spec and helper path.
- [x] **Diff coverage >= 80%** - N/A locally: E2E helper/spec/doc change; CI diff coverage is authoritative.
- [x] Coverage matrix updated - N/A: E2E selector-hardening change, no feature row added/removed/renamed.
- [x] All affected feature IDs from the matrix are listed in the PR description under `## Related` - N/A: no matrix feature ID applies.
- [x] No new external network dependencies introduced (mock backend used per [Testing Strategy](../gitbooks/developing/testing-strategy.md#mock-policy))
- [x] Manual smoke checklist updated if this touches release-cut surfaces ([`docs/RELEASE-MANUAL-SMOKE.md`](../docs/RELEASE-MANUAL-SMOKE.md)) - N/A: no release-cut surface.
- [x] Linked issue closed via `Closes #NNN` in the `## Related` section - N/A: this is a scoped slice that references #1861 without closing the broader audit issue.

## Impact

- Runtime impact: none outside stable `data-testid` attributes on the Cron Jobs panel.
- Test impact: cron E2E is less coupled to Tailwind classes and container structure.
- Compatibility: `waitForTestId` is documented as tauri-driver/DOM-backed; Mac2 specs should keep accessibility/text helpers unless IDs are mirrored into accessible labels.

## Related

- Refs #1861
- Follow-up PR(s)/TODOs: add stable hooks/migrations for the remaining settings, skills, conversation, onboarding, and notification E2E surfaces tracked by #1861.

### Linear Issue
- Key: N/A
- URL: N/A

### Commit & Branch
- Branch: `codex/1861-cron-e2e-testids`
- Commit SHA: `28eca40a3d2e3a75b61105887e4faf58d4c0866e`

### Validation Run
- [x] `pnpm --filter openhuman-app exec prettier --check src/components/settings/panels/CronJobsPanel.tsx test/e2e/helpers/element-helpers.ts test/e2e/specs/cron-jobs-flow.spec.ts` - passed
- [x] `pnpm typecheck` - passed
- [x] Focused tests: N/A, E2E spec migration not run locally
- [x] Rust fmt/check (if changed): `cargo fmt --all --check` - passed; `git diff --check` - passed
- [x] Tauri fmt/check (if changed): N/A

### Validation Blocked
- `command:` `pnpm --filter openhuman-app exec tsc -p test/tsconfig.e2e.json --noEmit`
- `error:` local command could not find `tsc` / `@wdio/globals/types` via that invocation
- `impact:` app-wide `pnpm typecheck` passes; remote E2E/TS jobs remain authoritative for the E2E tsconfig

### Behavior Changes
- Intended behavior change: none for users; E2E selectors now target stable hooks.
- User-visible effect: none.

### Parity Contract
- Legacy behavior preserved: cron load, refresh, pause/resume, run-history, and remove behavior unchanged.
- Guard/fallback/dispatch parity checks: spec still asserts the same UI and sidecar persistence behavior.

### Duplicate / Superseded PR Handling
- Duplicate PR(s): N/A
- Canonical PR: this PR
- Resolution (closed/superseded/updated): N/A

## Summary by CodeRabbit

* **Tests**
  * Added E2E helpers and updated cron-jobs flow to use stable test identifiers for more reliable UI interactions and polling.

* **Documentation**
  * Added guidance on stable test ID naming and how to use the new E2E helpers in the testing guide.

* **Maintenance**
  * Cron Jobs panel and controls now expose stable identifiers for testing (no user-facing behavior changes).

+### Stable test IDs
+
+Prefer stable `data-testid` hooks for UI affordances that E2E specs click or poll. Use the taxonomy `<surface>-<element>-<id?>`, for example:
+
+- `cron-jobs-panel`, `cron-refresh`
+- `cron-job-row-<jobId>`, `cron-job-toggle-<jobId>`, `cron-job-run-<jobId>`, `cron-job-view-runs-<jobId>`, `cron-job-remove-<jobId>`
+- `settings-nav-<routeId>`
+- `skill-row-<skillId>`, `skill-install-<skillId>`, `skill-uninstall-<skillId>`
+- `thread-row-<threadId>`, `new-thread-button`, `send-message-button`
+- `onboarding-next-button`
+
+Use `waitForTestId(testId)` and `clickTestId(testId)` from `element-helpers.ts` when a spec targets one of these hooks. Keep text selectors for user-visible copy assertions, not row/action discovery.
