feat: add Auto Run mode for full automated flow

- Background: add step completion waiting (promise-based), autoRun/resumeAutoRun
  chains steps 1→2 (pause for email) → 3→4→5→6→7→8→9 automatically
- Side Panel: add "Auto Run" button and "Continue Auto" bar for email pause point
- signup-page.js: add step 8 handler to click "继续" on OAuth consent page
- Fix all steps to reportComplete before form submit (prevents connection loss on navigation)
- qq-mail.js: fallback after 3 attempts to first matching email
- vps-panel.js: step 9 waits for "认证成功！" status badge
