orb-ui: app-based self-serve ui (#241)

orb-ui: self-serve ui

SignupStartOperator event created for "legacy" flow
where operator presses the button to start signup.
SignupStart now used to start signup/biometric capture:
- button press (v0 of self-serve)
- app button press by user (v1 of self-serve)
