[MS-1127] Multi-Factor ID: architecture groundwork

[alexandr-simprints]

JIRA ticket
Will be released in: 2025.4.0

Notable changes

This PR only contains the necessary groundwork to support the MF-ID in the Enrolment and Identification workflows. Considering the size of the feature, we would like to limit the scope to make PRs easier to review. What has been added/changed:

1. external-credential module

Adding new :feature:external-credential module that will contain everything related to the user-facing part of the MF-ID

2. Navigation

• Two navigation graphs were added: external (to enter the step) and internal (for sub-steps, the same way it is done with face).

3. Controller fragment + child fragments

• Controller fragment is in charge of the entire MF-ID 'step', and hosts the child fragments
• Child fragments are not yet implemented. Each fragment will get its own PR.

4. MF-ID Step added

• MF-ID step is added to the list of steps if enabled in the project configuration
• Only Enrolment and Identification flows may have the MF-ID step

5. Orchestrator Updates

• enrolmentSubjectId: String field is added. When building steps during Enrolment, the MF-ID step requires to know what subjectId to use if user links the credential. Previously, the subjectId was generated in SubjectFactory::buildSubjectFromCaptureResults called from CreateEnrolResponseUseCase:
  val subjectId = UUID.randomUUID().toString()
  Now, the same assignment is done in advance to allow passing it to the MF-ID step instead of dynamically updating the MF-ID step in Orcherstrator

Testing guidance

• Enable MF-ID in project configuration
• Start enrolment
• Verify that Scanner Selection screen is displayed after the biometric capture step

Additional work checklist

• Effect on other features and security has been considered
• Design document marked as "In development" (if applicable)
• External (Gitbook) and internal (Confluence) Documentation is up to date (or ticket created)
