feat: temp email API, duck API generation, remove debugger

- Add Temp Email API provider: poll verification codes via HTTP fetch
  instead of opening QQ/163 mail tabs, with MIME Base64 subject decoding
- Duck email generation via API: extract access_token on first run,
  then use quack.duckduckgo.com/api/email/addresses directly
- Remove chrome.debugger usage in Step 8: use content script
  simulateClick instead, eliminating "controlled by debugger" banner
- Detect phone verification page in Step 7 and skip to next run
- Fix bfcache error handling with automatic tab reload and retry
- Fix null entry crash in ensureAutomationWindowId
- Preserve tempApiUrl and duckToken across auto-run iterations
