feat(mfa): DSC as own factor type + fix selector collisions

- access-control: register DSC enrollment under factorType='DSC' instead of
  the legacy 'TOKEN' alias, hydrate / disable paths match on the same code.
  Pill labels in the picker and Hardware Token panel updated to 'Type · DSC'.
  service.ts MfaFactorType union adds 'DSC'.
- two-factor-authentication: initialise the delivery-method form at field
  declaration instead of inside ngOnInit so Angular's first change-detection
  pass doesn't fire 'Cannot find control' before the form is built.
- Rename duplicate component selectors that were tripping NG0912 at runtime:
  mifosx-notes-tab -> mifosx-{centers,clients,current-account,groups,loans,
  savings}-notes-tab; mifosx-unassign-staff-dialog -> mifosx-{clients,groups}-
  unassign-staff-dialog. Selectors aren't referenced in templates (route /
  dialog open), so the rename has no usage-site impact.
