Added third step of new access grant flow where user selects further passphrase option from this list:
- use existing passphrase
- set my project passphrase
- generate new passphrase
- enter new passphrase
Note: In case of 'use existing passphrase' option access grant will be generated and user will be redirected to success screen (not implemented yet).
