feat(platform): KYC flow - Rollup-facilitated UX

[betimshahini]

Why

To meet constraints of different providers as well as to streamline the user experience, improve trust and security of data, we need to add support for Rollup-facilitated KYC UX, where data is still managed fully by provider through APIs only (no UI)

What

• Create flows where, based on pre-existing templates, a KYC input flow is facilitated through Passport. This should be tied to the lifecycle of, but still separate from, the authorization screen and providing consent. Incorporate KYC data entry hints, where the data for some of the KYC inputs originates in user's connected accounts for them to choose to auto-fill KYC fields with.
• Create a configuration flow for apps intending to incorporate KYC into their authn/authz/verify flows. The pre-existing KYC template and region in which it applies should be configurable.

How

• UX design
