fix(virgool): switch from status_code to message check type with errors for JS cookies

The virgool.io site uses JS-generated cookies for anti-bot protection,
causing HTTP 200 for all URLs regardless of user existence. The
status_code check type always produced false positives.

Changes:
- Switch checkType from status_code to message so presence/absence
  strings are actually used for detection
- Add presenseStrs with profile-specific markers that won't match
  the JS cookie challenge page
- Add errors field to detect the JS cookie challenge page and report
  a meaningful error message
- Keep disabled: true as the site requires JS execution
