Bio Login Module

The main purpose of Bio Login is to capture the user's facial data and upload it to the server for biometric authentication.
The result of the upload can be monitored. Unlike the other modules, whose upload callback only confirms that the document reached the server, the Bio Login callback reports whether the document was approved — its backend flow is synchronous, so the verdict comes back with the response instead of arriving later through the event listener.

Between v1 and v2, the main difference lies only in the backend implementation.
Both versions support capturing the selfie either automatically (when the user is in the correct position and lighting) or manually (by pressing a button).
