fix: wait for login form to render before auto-fill (#201)

The Bloomreach login page is an Angular SPA that takes several seconds
to render after DOM content loads. The auto-fill was running immediately
after navigation with only 500ms per selector, causing it to silently
fail every time.

Changes:
- Use waitUntil: 'networkidle' instead of 'domcontentloaded' for login
  page navigation
- Add explicit waitForSelector for email input (10s timeout) before
  attempting auto-fill
- Increase default selector candidate timeout from 500ms to 3s to
  accommodate SPA rendering
